Question

The graphs below show the phenotypic distributions in two populations for a trait with 2 loci each with 2 arteles, allele frequencies of 0.5, and additive effects of 10.31. If phenotypic variance is explained by additive genetic variance, the expected ratio of phenotypes is 1:4:6:4:1 with a mean phenotype of 9.4. Which population will have a higher heritability for the trait? 7.5 8.1 8.7 9.3 9.9 10.5 11.1 7.5 8.1 8.7 9.3 9.9 10.5 11.1 A the right population because its distribution is closer to a 1:46:4:1 rati B. the right population because its distribution has a mean of 9.36 and a standard deviation of 0.60 the loft population because its distribution is closer to a normal distribution D. the left population because it has higher phenotypic variance and therefore higher additive genetic variance

Answer 1

The correct answer for the above question is D.The left population because it has higher phenotypic variance and therefore higher additive genetic variance.
