Question

If an adult dog has 78 chromosomes, the number of chromosomes in a dog's sperm cell will be ____
​

Answer 1

Answer:

If the dog in the question were to have 78 chromosomes in its sperm cells, it would contribute two sets to its offspring. When combined with the chromosomes in the egg cell, the offspring would end up with extra chromosomes. Therefore, both the sperm and the egg cells will have 39 chromosomes, one of each.

Answer 2

Answer:

Your answer would be 39
