Question asked by Filo student
A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Bb, Ee, and Hh that determine if gremlins have biting teeth (B), are evil (E), and have hair (H). In order to determine if the three genes are linked, a standard testcross was done, and the 1000 offspring had the following genotypes: 48 bb ee Hh 36 Bb ee Hh 400 bb Ee hh 426 Bb Ee Hh 46 bb ee hh 36 Bb ee hh 2 bb Ee Hh What is the recombination frequency between genes E and B? 10.0% 42.6% 9.4% 8.4% 0.6%
