Which best describes how to estimate heritability?
(a.) The regression slope of mean offspring phenotype versus mean parent phenotype
(b). The ratio of selection differential divided by selection response
(c). Both a and b are true
(d). Both a and b are false
Both a and b are true because which are responsible for the estimation of heritability

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 is true regarding dihybrid crosses? A. Each parent involved in the cross is heterozygous for at least one of the two genes being assessed. B. Two gene loci are assessed and the parents can be any genotype at these two loci. C. There are 9 different fertilization possibilities. D. The ratio 9:3:3:1 means that of the possible outcomes in offspring; 9/16 will express the dominant phenotype for both loci, 3/16 will express the dominant phenotype for...
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.
