Challenge Problems
Push your limits with challenges.
Question 1
You are studying two traits in peas, where one gene's alleles mask another's expression. If a certain cross results in a 12:3:1 phenotype ratio instead of the expected 9:3:3:1 skewed by epistasis, discuss the significance and implications for future studies.
💡 Hint: What does a deviation from expected ratios imply about gene relationships?
Question 2
Design a hypothetical crossing experiment between two linked genes with known recombination frequencies, hypothesize the resulting phenotypic ratios, and illustrate how crossing over might provide unexpected results.
💡 Hint: Consider how the spacing of genes affects crossing over frequencies.
