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. WebThe broad-sense heritability (H2) is calculated according to method of Lush (1940) as follows: H2 = ˙2 g ˙2 p The estimates of broad-sense heritability (H2) are categorised according to Robinson (1966) as follows: H2 Category x <30 Low 30 x <60 Medium 60 High Genetic advance (GA) is estimated and categorised according to Johnson et al., (1955 ...
