- Question #1 a. Explain why there is a non-Mendelian 2:1 yellow/agouti phenotypic ratio in this cross. b. What is the Raly gene? What does it encode? How does it relate to the lethality of Ay? c. A heterozygous mouse AAy does not produce enough pigment and it is yellow. Homozygous individuals die during development, but AAy heterozygous do not. Why? You may use any graphic aid to explain this, if necessary. This means that you may use a Punnett square or a forking segregation diagram, or computations with fractions.Question 1: In tomatoes, round fruit (O) is dominant to oblong fruit (o). Write as much as possible of the genotypes of: (A) A plant from a homozygous round-fruited stock (B) A plant from an oblong strain (C) A round-fruited plant which resulted from a testcross (D) A oblong-fruited plant which resulted from the cross of two round-fruited ones.QUESTION 5. The pedigree below follows the appearance of a rare autosomal dominant condition resulting in malformation of limbs through a family. What is the penetrance of this trait? i.e., What is the ratio between the number of individuals in the pedigree who display the trait (numerator) and the number of individuals you know from the pedigree must have the trait-determining genotype (denominator)? Enter your answer in the form of a fraction without any spaces. e.g., If your answer is “one-fourth”, enter: 1/4
