Question

Genetic X Fies Analysis of Crosses The pointed-ear trait in MendAliens is caused by an X-linked recessive mutant allele. Genetic X Files Problems a. A female MendAlien, Marge, with no ears (the normal condition) and whose male parent had pointed ears pairs with a male MendAlien with no ears and whose male parent also had pointed ears. The pointed ears phenotype looks like this: Pointed-ears phenotype Using e for the pointed-ears allele and Efor the normal no-ear allele, diagram the cross, and give the proportions of the phenotypes in the offspring that will have ears. (Give your answer separately for males and females.) b. Assume, instead, that the female MendAlien, in part a, pairs with a male MendAlien with pointed ears as follows: No ears (female) Ears (male) Diagram the cross, and give the proportion of the phenotypes in the offspring. (Give your answer separately for males and females.)
