Can a man with color blindness inherit a male Can a woman inherit a woman

Color blindness is inherited with X recessive. In general, only homozygous organisms can cause disease.

Therefore, the chance of women suffering from color blindness is relatively low, but it is not impossible. Males have a very high incidence of disease and are easily inherited. Therefore, most of the patients are male.

Both of the scenarios you are talking about are possible, it's just a matter of probability.

When a man is colorblind, if his spouse is not colorblind, there is a 50% chance of getting sick for boys and 50% for girls. If their spouse is also colorblind, that's the end of it, almost all children are colorblind, except, of course, genetic variations.

When a woman is colorblind, if her spouse is not colorblind, then among the children born, the probability of the boy being sick is 100%, and the probability of the girl being sick is 0, that is, the girl will not suffer from color blindness; When his or her spouse is colorblind, all of her children are colorblind.

In general, it is cross-inherited, and if the parents are color blind, it is possible to cause the disease in their children, especially in boys.

The above proportions are theoretical, but in fact they vary due to genetic variation or even loss.

Hope it helps!

Colorblind males cannot be passed on directly to their sons, but they can be passed on from daughters to grandchildren; Women carry the gene for color blindness that can be passed on to their daughters or to their sons, but daughters do not develop the disease.

A congenital color vision disorder. There are several types of color vision disorders, the most common being red-green color blindness. According to the theory of the three primary colors, any color in the visible spectrum can be composed of red, green, and blue.

If you can recognize all three primary colors, you are a normal person, and if you can't recognize all three primary colors, you are called total color blindness. Those who have a reduced ability to recognize any color are said to have weak colors, mainly red and green. If there is a primary color that cannot be recognized, it is called dichromism, mainly red color blindness and green color blindness.

Red-green color blindness is extremely common. Because patients do not have normal color discrimination from an early age, they are not easy to detect. Red-green color blindness is one of the most common associated genetic disorders in humans.

Red-green color blindness is thought to be determined by two pairs of genes on the X chromosome, the red color blind gene and the green color change gene. Because these two pairs of genes are tightly linked on the X chromosome, they are often represented by a genetic symbol. Red-green color blindness is inherited in an X-linked recessive manner.

Males have only one X chromosome, so only one color blindness gene is needed to exhibit color blindness. Females have two X chromosomes and need a pair of pathogenic alleles to behave abnormally. As a result, there are far more males than females with color blindness.

If a normal woman is married to a colorblind male, the father's colorblind gene can be passed on to their daughter on the X chromosome, but not to their son. The daughter then passes on the color blindness gene from her father to her son, a phenomenon called cross-inheritance. Because patients with red-green color blindness cannot distinguish between red and green, they are not suitable for work that requires color vision sensitivity such as art, textiles, printing and dyeing, and chemical engineering.

For example, in transportation, if workers are colorblind, they may not be able to distinguish color signals, which may lead to traffic accidents.

Color blindness is inherited by sex, and generally only males are inherited!!

The X chromosome allows genetic diseases to pass from male to female.

1 Congenital color blindness is often chained recessive, and is closely related to sex, because the inherited gene is on the sex chromosome, in general, the probability of male color blindness is much greater than that of female. And because the gene is recessive, a person with a color blindness gene may only be a carrier and not develop the disease, but he can pass the gene on to the next generation.

2 Generally speaking, the normal chromosome for males is (xy), the normal chromosome for females is (xx), the performance genes of dominant color blindness and recessive color blindness (color blindness gene carriers) are on sex chromosome x, congenital color blindness is chained recessive inheritance, so as long as a male gets a recessive color blindness gene, it can be manifested as color blindness, and a female gene is obtained from both parents, so even if you get a recessive color blindness gene, as long as the other gene is normal, you will become a color blindness gene carrier, without exhibiting color blindness.

3 When a normal male marries a colorblind woman, the incidence of color blindness is 1 2 for boys and 1 2 for girls who are recessive color blindness (carriers of the color blindness gene).

The incidence of recessive color blindness in a normal male married to a female color blind gene carrier is 1 4 in boys and 1 4 in girlsMen with color blindness marry normal women, and none of their children develop overt color blindness, but the incidence of implicit color blindness is 1 2.

Men with color blindness who marry women with color blindness gene carriers have a prevalence of 1 4 in women, males, and latent colors.

When a color-blind man marries a color-blind woman, the children born to him are inevitably colorblind.

4 In China, the rate of male color blindness, the rate of female color blindness, and the rate of color blindness gene carriers. In contrast, the incidence of congenital color blindness is about for males and females. Because color vision is generally not used as a condition for mate selection at the time of marriage, it is completely random, so the incidence of color blindness generally remains stable.

1) If a female (homozygous) with normal color vision marries a male with red-green color blindness, the son's color vision will be normal in their offspring; Although the daughter behaves normally, she is a carrier of the red-green color loss gene because she received a red-green color loss gene from her father, in which case the father's red green color loss gene is passed on to the daughter along with the X chromosome, but it must not be passed on to the son.

2) If the carrier of the red-green color loss gene in females and a normal male marry, among their offspring: the son has 1 2 normal and 1 2 red green color blindness; None of the daughters are colorblind, but 1 2 are carriers of the red-green color blindness gene. In this case, the son's red-green color blindness gene must have been passed down from his mother.

3) If a female carrier of the red-green color loss gene marries a male patient with red-green color blindness. Among their offspring: 1 2 daughters are normal, but all are carriers, and 1 2 are red-green color blind; The son has 1 2 normal and 1 2 is red-green color blind; In this case, the daughter's red-green color blindness gene comes half from the mother and half from the father; And the son's red-green color blindness gene must have come from his mother.

4) if a female patient with red-green color opallopsis marries a normal male, among their offspring; The daughters are normal, but they are carriers, and the sons are all red-green color blind. In this case, it was the mother who passed the red-green color blindness gene to her son along with the X chromosome. Through the analysis of the above four mating results, we can see that the red-green color blindness gene in a male is passed from the mother to his daughter.

It can be seen that the red-green color blindness gene is transmitted from female to male. This genetic trait is called cross-inheritance in genetics.

In fact, there is no need to pay special attention, color blindness will not be a defect in life. As long as it's not total color blindness, it's not a defect.

1.Colorblind men are < with normal women; Non-carriers"; Married, the son is definitely normal; The daughter is definitely a carrier <; Although normal, it is possible that her son is colorblind";

2.A normal male marries a female carrier, and his daughter has a 1 2 probability of being normal and 1 2 of a year being a carrier; The son has a 1 2 chance of normal, a 1 2 chance of color blindness, and 3Female colorblind marries a normal man, and the son is definitely colorblind; The daughter is definitely the carrier, 4Male colorblind marrying a female carrier has a 1 2 probability of normal son and 1 2 probability of color blindness; Daughters have a 1 2 chance of being color blind and 1 2 of a year being carriers. If the boy is normal, there will be no patients among his children, and if the girl has normal color vision, she will be a carrier, 5Male color blindness and female color blindness are matched, and both children and women are colorblind.

Color blindness is an X-linked recessive genetic disorder. Patients are not able to distinguish colors correctly. The color blindness gene that determines the condition is recessive and is located on the X chromosome.

The sex chromosomes of females are xx, the genotype of female colorblind patients is x"x", and the carrier is x'x. , x"x" for normal women. The sex chromosomes of males are male, and x'y is normal male.

Because it is X-linked recessive, the incidence of color blindness in men is much greater than that in women. Male patients are often seen in the population. Cross-inheritance can be seen in the pedigree.

You are not colorblind, you are married, and there will be 1 2 years of onward onspring sons. The daughter does not get sick, but 1 2 of them are carriers. If you are color blind, then after your marriage, the daughter of your offspring has l 2 likely to develop the disease, 1 2 is the carrier, and the son also has 1 2 the disease, 1 2 is normal.

I remember it was Chang Yin, I wasn't sure, I asked if it was Chang Yin, and the teacher told me that it was Chang Yin!

They are all inherited with x recessive, so there are more males and fewer females.
