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

Whatever is the chromosome number in somatic cell, in gametes of the same species, i.e. in egg/sperm chromosome number will be reduced to half.

Therefore, the number of chromosomes in sperm will be 16 (n) in an animal whose somatic cell has 32 (2n) chromosomes.

A sperm cell from an animal with 2n=32 chromosomes would contain 16 chromosomes. A haploid cell would have half the number of chromosomes as the diploid cell, so a haploid cell from this animal would have 16 chromosomes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
