Question

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.

Answer 1

Germ-line mutations are mutations that would be passed down to future generations, and recombinations are where the information each parent passes down to the offspring is shuffled.

The genetic variation would have to come from random events: False
Only alternate generations would express any genetic variable: False
Body cell mutations would be the only source of heritable genetic variation: False
There would be no new heritable genetic variation possible in the population: True

Answer 2

Answer: The answer is D. There would be no new heritable genetic variation possible in the population.
