Question 1

The alleles of linked genes tend to ________.
◦ segregate together during gamete production
◦ assort independently
◦ be mutated more often than unlinked genes
◦ experience a higher rate of crossing over
◦ assort independently and show a higher rate of crossing over

Question 2

The order of genes on a plant chromosome is A, B, and D, where A and B have a recombination frequency of 0.2, and B and D have a recombination frequency of 0.3. A pure-breeding plant that has the dominant A and D phenotypes with a recessive b phenotype is crossed to a pure-breeding plant that has the recessive a and d phenotypes with the dominant B phenotype. The resulting hybrid is crossed to a plant that has all three recessive phenotypes. Under the assumption that the value for interference in this region is zero, what percentage of each progeny type would result from a single crossover between B and D?
◦ 24% ABd/ abd; 24% abD/ abd
◦ 7% ABD/ abd; 7% abd/ abd
◦ 12% Abd/ abd; 12% aBD/ abd
◦ 50% AbD/ abd; 50% aBd/ abd
◦ 9% ABD/ abd; 9% abd/ abd
