Genetic recombination

1. The genotypic and phenotypic ratios derived in this section are all based on selfing with no selection. Breeders do select. We are going to cross two plants differing at only one gene (BB x bb) and begin selection for the best phenotype began in F2 and continue on for several generations. Discuss how the outcomes would change if the B gene had: dominant gene action,
additive gene action, and overdominant gene action
2. Does linkage help or hinder the breeding of crops? Write a half – full page page discussing this issue.
