Linked Genes and Gamete Genotypes
Alleles A and B are linked on chromosome 1 (arranged as A-B and a-b). Alleles C and D are linked on chromosome 2 (arranged as C-D and c-d). If no crossover events occur between either set of genes, which of the following gamete genotypes could NOT be produced by an individual heterozygous at each locus?
A
A-B; C-d
B
A-B; C-D
C
A-B; c-d
D
a-b; c-d
