a. Why is heritability necessary for natural selection? How would you expect a trait for which there is no resemblance between parents and offspring to change over time? b. Why is differential success among organisms with different variants of a trait necessary for natural selection? How would you expect a trait for which there is no differential success to change over time?

Which of the following are true of modifying and epistatic genes in regard to genetic diseases? (1) Modifying genes can account for the severity of a genetic disease Modifying genes do not completely mask genes for a genetic disease. Epistatic genes may cause a disease by masking normal genes. The expression of modifying genes can be affected by environmental factors.
