Heritability

proportion of phenotype passed to the next generation

Why do quantitative geneticists focus on A in the context of P = G + E (briefly)?

A is the only genetic component passed from generation to generation and therefore the
target of selection

Repeatability

The likelihood that an individual will repeat the same phenotype

All semester we have been studying different types of selection. What (briefly) is the end
result of selection at the level of DNA

Selection modifies allele frequencies so we expect to see the DNA sequence for genes
affecting the trait of interest to be changing to the “good” allele(s)

All semester we have been studying Quantitative Genetics. What (briefly) is a quantitative trait

A trait that is measured having a continuous distribution and a range of phenotypes
