How many eggs do you think were released by the ovary of a female dog which gave birth to 6 puppies?

उत्तर
Dogs have multiple births, so several eggs are released and develop at the same time. If fertilised, each egg implants in the uterine wall and develops into a puppy. The gestation period in dogs is about 56 to 72 days, and a typical litter contains approximately six puppies, although this number may vary depending on the breed. Therefore, it can be concluded that approximately 6 eggs were released by the ovary, resulting in the birth of 6 puppies.
