Question

why do some organisns like dogs and rats give births to more than one offsprings at a time whereas humans Usually give birth to just one offsprings?​

Answer 1

Answer:

Two reasons—the number of eggs the female releases, and the shape of the uterus.

Female cats are induced ovulators; when they mate, they release egg(s) from their ovaries. And they release more than one at a time.

Dogs have a cycle and ovulate at a specific time, like humans do. But they also release multiple eggs.

Answer 2

while doing sexual reproduction only one sperm will go from penis to ovum
