1 A Wild type fruit fly (heterozygous for gray body and normal wings) is mated with a black fly with vestigial wings. OFFSPRING: wild type 785- black-vestigial 158- black- normal wings 162- gray body-vestigial wings What is the recombination frequency between these genes?

2 A Wild type fruit fly (heterozygous for gray body and red eyes) is mated with a black fly with purple eyes. OFFSPRING: gray body/red eyes black body/purple eyes 49- gray body/purple eyes 45- black body/red-eyes What is the recombination frequency between these genes?

3 Determine the sequence of genes along a chromosome based on the following recombination frequencies: A-B = 8 map units A-C = 28 map units A-D = 25 map units B-C = 20 map units B-D = 33 map units

4 Determine the sequence of genes along a chromosome based on the following recombination frequencies: A-C = 20 map units A-D = 10 map units B-C = 15 map units B-D = 5 map units

Linkage, Sex linkage, Pedigrees. Linked genes We know two traits should assort independently. Why? So, offspring phenotype ratios should be: –9:3:3:1.
