If an intestinal cell in a dog contains 78 chromosomes, how many chromosomes would be found in the dog\'s skin cells or sperm cells? What cell division process would make each kind of cell? [Assume no mutations have occurred).

Solution

Answer : 78 chromosomes would be found in the dog\'s skin cells and 39 chromosomes would be found in dog\'s sperm cells. The skin cell is somatic cell, so mitotic cell division takes place. The sperm cell is a gamete so meiosis takes place.
