Autosomal Recessive Inheritance We learned in the Linkage Mapping lab module the conventions for representing alleles in fruit flies. Recall that we use one to three letters, and the case (upper or lower) is determined by whether the mutant allele is recessive or dominant. Additionally, we add a "+" as a superscript to indicate the wild-type ("normal") allele. For example, if a new mutant phenotype is recessive, we can represent the recessive allele as m. Then the wild-type allele is mt, and m+ > m. Based on the rule of dominance, we can predict phenotypes based on genotypes: mm Wild type Wild type Mutant m+m mmarrow_forwardIdentify gene 1( bl, pr, vg) Identity gene 2 ( bl, pr, vg) Identify gene 3 ( bl, pr, vg)arrow_forward
