Which of the following best describes the advantage of sexual reproduction?
All offspring will contain only the best traits, so they will become stronger in each
generation.
Offspring will be identical to their parents, which increases strength of a population.
Offspring will be a mixture of their parent’s traits, increasing variation in the
population.
Males and females will find similar partners which will help to decrease variation in
the population
Genetic variation is biologically important in a population because
it increase the survival rate of a population in a changing environment.
it looks better than the same thing over and over.
it decreases the survival rate of a population which helps eliminate competition.
actually, genetic variation is not very important.
