True or false: Natural selection is limited by the genetic info in the original created kind since it can’t create any new info. Natural selection can act only to remove genetic info from a population.

In a population of gray squirrels, some individuals are larger than others. How is genetic drift likely to affect this population without any pressure from the environment?

Back

Genetic drift is random, so it is impossible to predict.

Back

True

Front

An organism’s genotype is the combination of alleles that it has inherited from its parents

Back

True

Front

True or false: An organism’s phenotype consists of the traits coded for by the alleles in its genotype

Back

True

Front

True or false: Genetic drift is measured by the ratio of organisms with a specific phenotype

Back
