A
P=G+Environment
4
Q
Effect of selection on random mating
A
Selection prior = 2x the allele frequency than post random mating
5
Q
heritability broad sense
A
proportion of phenotypic variance due to heredity (ratio of genotypic variance to phenotypic variance)
6
Q
heritability narrow sense
A
proportion of phenotypic variance that will respond to selection (due to additive effects of genes)
7
Q
transgressive segregation
A
offspring with more extreme expression of quantitative trait than parents
8
Q

A
organism consisting of tissues of different genetic constitution
