What are the colors of red and green in the eyes of red green color blindness?

Yellow, either earthy yellow or yellow.

What is the difference between the colors we see when we are blind? It's heart-wrenching to watch!

1. Red-green color blindness refers to the inability to distinguish between red and green, and they see the entire spectrum as two basic hues: yellow for the long-wave (red, orange, yellow, green) and blue for the short-wave (cyan, blue, violet). That is, they can distinguish between yellow and blue, and in their eyes the color is all a transition between yellow and blue, and red and green are missing.

2. Types of color blindness:

1. Total color blindness. It is a complete cone cell dysfunction, and the colorful world is gray in its eyes, just like watching a black-and-white TV, with only light and dark, and no color difference.

2. Red blindness, also known as the first color blindness, has the highest incidence. Patients are mainly unable to distinguish red, red and dark green, blue and purplish, and purple, and often perceive green as yellow, purple as blue, and green and blue as white.

3. Green blindness. Also known as second color blindness, people cannot distinguish between pale green and dark red, purple and cyan blue, purple and gray, and perceive green as gray or dark black.

4. Blue-yellow blindness, also known as the third color blindness, patients are confused with blue and yellow, and red and green can be distinguished, which is rare.

5. The whole color is weak, also known as red, green, blue and yellow weak. The degree of color vision impairment is lower than that of total color blindness, and there is no abnormality in visual acuity, nor other complications of total color blindness, and it can distinguish when the color of the object is dark and distinct; If the color is light and not saturated, it is difficult to distinguish and is rare in patients.

6. Some colors are weak, including red weak (first color weak), green weak (second color weak) and blue and yellow weak (third color weak), etc., among which red and green are more common, patients have poor sensitivity to red and green, and their color discrimination ability is close to red-green blindness when the lighting is poor; However, when the color of the substance is deep, vivid and the illumination is good, its color discrimination ability is close to normal.

Cause: Inability to distinguish between red and green colors is a congenital color vision disorder. The gene that controls red-green color blindness is located on the X chromosome and is recessive, usually denoted by XB, and the Y chromosome is too short to lack the homologous segment corresponding to the X chromosome and there is no gene to control color blindness.

Red-green color blindness is inherited in a cross-inherited manner.

According to the theory of 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. It is thought that red-green color blindness is determined by the presence of two pairs of genes on the X chromosome, namely the red color loss gene and the green color color gene culture.

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, so a pair of pathogenic alleles are needed to behave abnormally.

Answer]: C Erythromycin is a macrolide antibiotic, the antibacterial spectrum is similar to penicillin, and has a strong inhibitory effect on gram-positive bacteria, such as staphylococcus, Streptococcus pyogenes, Streptococcus greenis, Streptococcus pneumoniae, Streptococcus faecalis, hemolytic streptococcus, Clostridium, diphtheria bacillus, Bacillus anthracis, etc. It also has a certain inhibitory effect on gram-negative sclerotinia sclerotia, such as gonorrhea, spirobacteria, pertussis, brucella, legionella, meningococcal and Haemophilus influenzae, bacteroides, some dysentery bacilli and Escherichia coli, etc., and has no anti-tuberculosis effect.

In addition, it has inhibitory effect on mycoplasma, actinomycetes, spirochetes, rickettsia, chlamydia, Nocardia, a few mycobacteria and amoebic protozoa. Staphylococcus and Streptococcus bacteria such as Staphylococcus aureus are easily resistant to the product. It is characterized by penicillin-resistant strains that change sensitivity to this product.

The mechanism of action is mainly combined with the 50S subunit of ribonucleosomes, inhibiting peptidyltransferase, affecting the translocation process of ribonucleosomes, hindering the growth of peptide chains, and inhibiting the synthesis of bacterial proteins.
