Question 3 (6 pts). In hogs, colored hair (H) is completely dominant to colorless (h) and bent tails (B) are completely dominant to straight tails (b). There are no interlocus interactions Penetrance and expressivity are 100%. The two loci are not sex-linked. The phenotypes and frequencies of progeny following testcrosses of hogs 1 and 2 to a double recessive genotype (hh bb)are listed in the table Testcross Progeny of hog 1 134 Phenotype colored, bent colored, straight colorless, bent colorless, straight TOTALS Testcross Progeny of hog 2 28 335 358 30 751 12 143 300 a. For testcross progeny of hog 1, what are the recombinant classes or recombinant phenotypes in the progeny? b. For testcross progeny of hog 2, what are parental classes or parental phenotypes in the progeny? c. For hog 2, are the recessive alleles in the cis or trans configuration? d. (2 pts) How far apart (in cM) are the two gene loci on the genetic map? You can use data from progeny of hog 1 or hog 2. Show your work e. For hog 1, Uf the two loci were sorting or segregating independently, what fraction of the testcross progeny would you expect to have colored hair and straight tails?
