What would happen if there were no germ-line mutations or genetic recombination possible in a population? (2 points) genetic variation would have to come from random events. only alternate generations would express any genetic variation. body cell mutations would be the only source of heritable genetic variation. there would be no new heritable genetic variation possible in the population.

The diagram shows a fossil of an ancient whale skull and a skull of a present-day whale. the ancient whale is extinct and is believed to be an ancestor of the present-day whale. what do these skulls most likely show that supports darwin’s theory of evolution? all populations can adapt and survive. only some organisms have a common ancestor. populations change slowly over time. populations rapidly become extinct.
