Three genes in fruit flies affect a particular trait, andone dominant allele of each gene is necessary to get awild-type phenotype.a. What phenotypic ratios would you predict amongthe progeny if you crossed triply heterozygous flies?b. You cross a particular wild-type male in successionwith three tester strains. In the cross with one testerstrain (AA bb cc), only 1/4 of the progeny are wildtype. In the crosses involving the other two testerstrains (aa BB cc and aa bb CC), half of the progeny are wild type. What is the genotype of thewild-type male?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
