The epithelial cells in the skin of an animal have 24 chromosomes. How many chromosomes are present in the gametes of this anima
mrs_skeptik [129]

Answer:

There will be 12 chromosomes

Explanation:

We have given that The epithelial cells in the skin of an animal have 24 chromosomes

We have to find the number of chromosomes present in the gametes of this animal

We know that number of chromosomes present in the gametes is given by

\frac{number\ of\ chromosmes\ present\ in\ skin}{2}

So number of chromosomes in gametes =\frac{24}{2}=12chromosomes

The major role meiosis plays in chromosomal inheritance is to
andrezito [222]

Answer:

Doubles the amount of DNA and reduces the chromosome number from 2N to N.

Explanation:

Meiosis is a cell division in which one cell divides into 2 cells in the first meiotic division and then these two cells divide into two more cells so overall 4 cells are produced from one cell. This division occurs in gamete cells.

First, the amount of DNA gets double by converting the single-stranded DNA into double-stranded DNA. Then the homologous chromosomes get separated into two different cells in the first meiotic division and till now the chromosome number is 2N.  

After the second meiotic division, each sister chromatids of a chromosome gets separated into separate cells and the chromosome number in daughter cells becomes 1 N. So the major role of meiosis is to double the DNA mount and reduce the chromosome number by half in all daughter cells.
