Question

How many chromosomes are in a sperm cell from an animal whose somatic cells have 32 chromosomes (2n=32)? If 2n=32, how many chromosomes are in a haploid cell?

Answer 1

Germ cells have only half the number of chromosomes as a diploid cell one of each pair - and are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y.
