D3.2.12: Explain how unlinked genes segregate and assort independently in meiosis. D3.2.13: Predict the inheritance of pairs of unlinked genes in dihybrid crosses. D3.2.14: Predict genotypic and phenotypic ratios in dihybrid crosses of unlinked autosomal genes using Punnett grids. D3.2.15: Explain why linked genes fail to assort independently. D3.2.16: Deduce genotypic and phenotypic possibilities of crosses of individuals heterozygous for two traits with those homozygous recessive for both traits in both linked and unlinked genes. D3.2.17: Calculate statistical significance of observed vs calculated data using chi-squared tests.
