Question 1 5 points Save The following mouse pedigree shows the segregation of both a dominant and a recessive trait. (Assume all phenotypes are completely penetrant). Draw this out: 1st Generation: female who is affected with dominant disorder only mates with male who is affected with the recessive disorder only. 2nd generation: 1 daughter and 1 son. Daughter is affected with dominant disorder only. Son is not affected with either disorder. What is the genotype of the daughter in generation 2? For your answer, use D to designate the allele for the dominant trait (with d representing the corresponding wild type allele) and r to designate the allele for the recessive trait (with R representing the corresponding wild type allele).

(Assume all phenotypes are completely penetrant). Draw this out (same as above): 1st Generation: female who is affected with dominant disorder only mates with male who is affected with the recessive disorder only. 2nd generation: 1 daughter and 1 son. Daughter is affected with dominant disorder only. Son is not affected with either disorder. It turns out both genes are 30 map units apart on the same autosome. If the siblings in generation 2 mated, predict the probability that a progeny mouse will be affected by both disorders. (Answers should be in decimal form)...
