Explanation:
Detailed explanation-1: -A cow has 60 chromosomes in one of its somatic cells.
Detailed explanation-2: -So, the germ cells will have 2 x 16 = 32 chromosomes.
Detailed explanation-3: -If a diploid cell contains 40 chromosomes, then the haploid cell contains 20 number of chromosomes. 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.
