How does reproduction in humans compare to reproduction and other animals such as fish, birds and reptiles?

It compares because all of them reproduce the same way with varied offspring instead of identical.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
