Broad-sense heritability h2

WebQuestion: Because adult body mass influences many other aspects of biology, you are interested in the degree to which it is influenced by genetic variation. You wish to use an available colony of mice, but you cannot clone them and therefore cannot estimate broad sense heritability, H2. WebQuestion: Broad sense heritability differs from narrow sense heritability in that: A for broad sense heritability, VG includes only additive effects of alleles B. for broad sense heritability, VG includes additive, dominance, and epistatic effects C. broad sense heritability includes only components of variance that cause offspring to resemble …
