Summary Introduction
To determine: The different
Introduction: Recombination is the process that is exclusive to the meiotic division as it allows the exchange of genetic material between the non-homologous chromosomes. The recombination process is responsible for the shuffling of the characters and producing a zygote that is different from both the parents but have the chromosomes from both the parents.

What are the expected phenotypic ratios from the following cross:Tt Rr yy Aa × Tt rr YY Aa, where T = tall, t = dwarf, R = round,r = wrinkled, Y = yellow, y = green, A = axial, a = terminal; T, R,Y, and A are dominant alleles. Note: Consider using the multiplication method in answering this problem
Based on the information you discovered in the previous problem, answer the following:a. A female fruit fly with genotype Tt nn is mated toa male of genotype Tt Nn. What is the probabilitythat any one of their offspring will have normalphenotypes for both characters?b. What phenotypes would you expect among the offspring of this cross? If you obtained 200 progeny, howmany of each phenotypic class would you expect?
