In studying the inheritance of flower length in tobacco species (Nicotiana sp.), the total phenotypic and

environmental variances were estimated to be 130.5

and 42 respectively.

1.What is the total genotypic variance (Vg

)?

2.Calculate the additive genetic variance if the

dominance variance was 11.5…

3.Estimate the narrow sense heritability if the

dominance variance was 11.5.

4.What is the broad sense heritability of the trait?​
