Do the reproductive cells contain the same number of chromosoms as the body cells?
No. A sperm cell and an egg cell released from an ovary contain half the chromosomes as other cells until the sperm enters the egg cell and its chromosomes join that of the egg. At that point the egg cell becomes a new individual with a full complement of chromosomes. In humans a person gets 23 chromosomes from the mother and 23 from the father for a total of 46.
