If the diploid number of chromosomes of a dog is 78, how many chromosomes would be in each gamete at the end of meiosis?
|
|
39 chromosomes
|
|
|
46 chromosomes
|
|
|
78 chromosomes
|
|
|
156 chromosomes

Explanation:
Detailed explanation-1: -So, if there are a total of 78 chromosomes then half of its number (half of 78) is 39 chromosomes are present in the female gamete or egg cell. So, the egg cell will have 39 numbers of chromosomes. Therefore, the answer is 39 chromosomes would be present in its egg cell.
Detailed explanation-2: -A meiocyte is diploid which undergoes meiosis to form haploid gametes. Gametes in turn fuse to form the diploid zygote. So the zygote of the dog will have the same number of the chromosomes as the meiocytes ie., 78.
Detailed explanation-3: -A dog (Canis familiaris) has 78 diploid number of chromosomes.
