When is a chi square analysis is applied to solve a linkage problem, explain why an independent assortment hypothesis is proposed. An independent assortment hypothesis is proposed because it enables us to calculate the expected values based on mendel's ratios. Using the observed and expected values, we can calculate whether or not the deviations between the observed and expected values are too large to occur as a matter of chance. if the deviations are very large, we reject the hypothesis of i...

Bio 235 Exam II Questions With 100% Correct Answers Complementary Gene Action Genes working in tandem to produce a particular trait. Duplicate Recessive Epistasis 9:7 ratio, either allele can mask another hypostatic gene's expression. Complementation Mutation in both genes work together to produce a different expected phenotype. Noncomplementation Mutations occur in the same gene to produce the same phenotype. When do two genes assort independently? When they are located on different...
