WebQuestion 1 The next two questions refer to the test cross data provided below? AaBb x aabb Offspring genotypes and numbers are: Aabb 65 aaBb 59 aabb 41 AaBb 35 Which offspring represent the results involving the "parental, non-recombinant" gametes? WebThe cross obtains AaBB : AaBb : Aabb genotypes in 1: 2: 1 ratio. Genotype "aabb" is not the product of this cross. Thus, the correct answer is option B.
