Sperm cells are about to be made from a cell with 66 chromosomes. How many chromosomes will the sperm cells have?
Sindrei [870]

Answer:

33

Explanation:

Gametes (sperm or egg) have half the chromosome of a diploid cell. That's why they are haploid cells.

If chromosomes come from a cell with 66 chromosomes, sperm will have 66/2 = 33.

That's why us humans have 46 chromosomes, but our egg or sperm has only 46/2 = 23 chromosomes.
