Question

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

Answer 1

39

I hope this helps

Answer 2

39

Step-by-step explanation:

Well with humans, each parent has half of the chromosomes that the baby will have, the sperm has half and the egg has the other set. So, I assume that if the puppy doesn't end up with any extra or less chromosome, it will get half of them from the sperm.
