A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for linked genes with alleles Bb, Ee, and Hh that determine if gremlins have biting teeth (B), are evil (E), have hair (H). In order to determine if the three genes are linked, a standard testcross was done, and 1000 offspring had the following genotypes: $$\begin{array} { l l } 48 & \text { bb ee } \mathrm { Hh } \\36 & \text { Bb ee hh } \\400 & \text { Bb ee } \mathrm { Hh } \\4 & \text { Bb Ee Hh } \\426 & \text { bb Ee hh } \\46 & \text { Bb Ee hh } \\38 & \text { bb Ee Hh } \\2 & \text { bb ee hh }\end{array}$$ What is the recombination frequency between genes E and B?

Assuming three genes are linked, how many recombinant genotypes would you expect and at what frequency?

In sweet peas, the genes for flower color and pollen grain shape are 11 cM apart. A pure- breeding purple flowering plant with round pollen grains is crossed to a pure- breeding red flowering plant with long pollen grains. The resulting F1 offspring are all purple flowering plants with long pollen grains. What percent of offspring from a test cross analysis of the F1 individuals would you expect to be red flowering plants with long pollen grains?
