NEET BIOLOGY

Detailed explanation-1: -Therefore, 19 chromosomes are inherited from each parent. Gametes (haploid) have 19 chromosomes.

Detailed explanation-2: -Tigers = are diploid animals just like uS, with autosomes and one pair of sex chromosomes a.In tiger skin cell at the start of interphase, how many chromosomes are present?

Detailed explanation-3: -In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number. In humans, n = 23.

Detailed explanation-4: -As we know that the genetic information in a diploid cell is reduced by half in order to produce a haploid gamete, we should be able to work out the number of chromosomes in a haploid cell by dividing the diploid chromosome number by two.

Detailed explanation-5: -The haploid number in humans is given as 2n=46, n = 23, this is because the haploid human cells possess one set of 23 chromosomes – 22 sets of autosomal chromosomes (non-sex chromosomes) and 1 set of sex chromosomes.
