AP BIOLOGY

Detailed explanation-1: -The investigations on the goat worked by Sokolov (’30), Shiwago (’31), Krallinger (’31) and Berry (’38) agree in respect of the number of chromosomes, finding 60 chromosomes for the diploid and 30 for the haploid.

Detailed explanation-2: -so an animal with a diploid number of chromosomes equal to 30 will produce four gametes. Each gamete will contain 15 chromosomes due to meiosis.

Detailed explanation-3: -The total number of chromosomes is referred to as the chromosome number. 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.

Detailed explanation-4: -The haploid cells contain half the number of chromosomes as the diploid cells. Thus, if a diploid cell contains 40 chromosomes, then the haploid cell will contain 20 chromosomes.

Detailed explanation-5: –Number of Chromatids is 64 since its replication of chromosomes and cell has split so, n (haploid) so the number of chromosomes would be 32.
