Question

The egg of an animal contains 10 chromosomes,of which one is x-chromosome. How many autosomes would there be in the karyotype of this animal

Answer 1

Karyotype is the number and appearance of chromosomes in a nucleus of somatic cell. Somatic cells are diploid cells which make up the body. They have two sets of chromosomes. So, if an egg cell (gamete cell) which is a haploid cell (with single set of chromosomes)has 10 chromosome, then number of chromosomes present  in a somatic cell will be 20 chromosomes . As egg cells are produced by female body, then among 20 chromosomes, two  X chromosomes will be present.  So, karyotpe of that animals will be showing 20 chromosomes. 

There will be 9 pairs of autosomes in the karyotype of this animal.

if you see anything wrong then please comment.
