Let’s brush up on mapping. For questions 1-8, pure-breeding P0 animals were mated to generate F1 animals heterozygous at the B and W genes. The heterozygous F1 animals were test-crossed and yielded progeny with the phenotypes below. Mutations in the B gene (b) cause a “no bristles” phenotype. Mutations in the W gene (w) cause a “no wings” phenotype. Both genes are haplosufficient. 45% normal bristles, normal wings 45% no bristles, no wings 5% no bristles, normal wings 5% normal bristles, no wings The numbers above suggest that the B and W genes are linked. What ratio of progeny would you have expected to see if B and W were on different chromosomes?
