Q1. Measurements on ear length were obtained from two populations of corn-one inbred variety and a randomly pollinated population at first derived from a cross between two inbred strains. The phenotypic variances were 9.4 cm2 for the inbred strain and 26.4 cm2 for the randomly pollinated population. Guess the broad sense heritability of ear length in these populations.
Q2. The loci sh (shrunken kernels), wx (waxy endosperm) and gl (glossy leaves) are located on chromosome 3 in maize. The approximate map distances are 30cM between sh and wx, and 10cM between wx and gl. What are the usual frequencies of the gametes from a plant with the genotype Sh Wx Gl / sh wx gl if;
a. If there is no interference?
b. If there is an interference of 0.6?
