$14$a$.$ In conducting a common garden experiment with ragweed plants you calculate phenotypic and genotypic variance estimates on plant height. What are the broad and narrow sense heritability of plant

height in this population? $(3)$

$14$b$.$ In a selection experiment involving this population of plants, you are selecting for greater height. If the mean height of this population is $151$ cm and the mean height of the breeding population is $194$ cm $,$ what would the mean height of the population be in the next generation? $(3)15.$ You are studying a quantitative character, weight in marsh monkeys. You have determined that this characteristic is due to an additive interaction between two genes. Individuals that are $\backslash (\backslash$mathrm$\{$AA$\}$: $\backslash$mathrm$\{$BB$\}\backslash )$ are $24$ kg while individuals with the genotype aa:bb are $16$ kg $.$ Each functional allele $($capital letter$)$ adds equally to

weight. The allele frequencies for each locus are provided below and both loci are in Hardy$-$Weinberg equilibrium and independently assorting. Provide the size distribution of the population. $(6)$
