How can diploid be judged?

Diploidy, as the name suggests, is two sets of chromosomes, and when there are three or more sets of chromosomes, it is called polyploidy.

Polyploidy can determine the number of chromosomes according to the definition of chromosomes: a group of non-homologous chromosomes in a cell, they are different in morphology and function, but carry all the information that controls the growth and development, heredity and variation of an organism, such a group of chromosomes is called a chromosome group.

That is, to count the number of homologous chromosomes (if it is a high school image problem, in the general image: chromosomes of the same size and different colors are homologous chromosomes), and there are as many homologous chromosomes as there are chromosome sets.

Both diploid and polyploid are developed from a fertilized egg and contain two sets of chromosomes.

1. Haploid is developed from gametes, and haploids can have multiple sets of chromosomes.

There will be hints in the general questions).

2. After excluding haploidy, the analysis is carried out, and judging the ploidy is actually judging the number of chromosomes in the somatic cells of a certain individual. As there are no homologous chromosomes in one set of chromosomes.

The number of homologous chromosomes becomes the main basis for judging the number of chromosomes, that is, judging how many ploids a certain body is.

3. A and A, A and A are the same genes, listed on the homologous chromosome, and A and A are alleles.

Also listed on homologous chromosomes. Several sails of the same letter (whether uppercase or lowercase) already have several homologous chromosomes, which are called several ploidies. Therefore, AA is two acres of homologous chromosomes with two chromosome sets, which is called diploid.

4. AAAA is 4 chromosomes of the same Xun car base source, including 4 chromosome groups, called tetraploidy.

5. AAABBBCCC is 3 homologous chromosomes with 3 chromosome groups, which is called triploidy.

6. AABCCDD contains 2 chromosome sets, which is called diploid. Others can be so on.

1. Diploid is diploid. Neither haploid nor polyploid.

Chromosomal ploidy refers to the number of homologous chromosomes within a somatic cell. Somatic cells with only one set of homologous chromosomes are called "haploids". An organism that has two sets of chromosomes in a somatic cell is a "diploid" organism.

2. If the somatic cell contains three or more chromosome groups, it is a "polyploid" organism.

Any organism that develops from a fertilized egg and contains two sets of chromosomes in its somatic cells is called diploid.

Polyploidy is one that has more than two sets of chromosomes.

What are diploid, aneuploidy, tetraploidy, hyperploid in the DNA quantitative cytology examination report?

Hello, glad to answer for you. DNA quantitative cytology: The presence of DNA aneuploidy is a specific indicator to distinguish benign and reverting malignant tumors, with benign tumor cells showing tetraploidy increase and malignant tumor cells showing aneuploidy increase. The number of dyes and omissions is several ploids, people are diploid, aneuploidy is odd, and hyperploidy is more than 3 chromosome groups.
