Hi,(adsbygoogle = window.adsbygoogle || []).push({});

My Question:

Assume that all phenotypic variance in seed weight in beans is genetically determined and is additive. From a population in which the mean seed weight was 0.88g, a farmer selected two seeds, each weighing 1.02g. He planted these and crossed the resulting plants to each other, then collected and weighed their seeds. The mean weight of their seeds was 0.96g. What is the narrow-sense heritability of seed weight?

Work

I know that I'm supposed to use this equation:

h^2= Va/Vt, where

Va is the variance due to additive alleles

Vt is the total variance, so I did this

h^2= .88/.96 =.92

Is this correct??

Thank You
