Gene Linkage in Drosophila | T. H. Morgan Experiment | Complete Linkage | 2025

Gene Linkage in Drosophila In Drosophila, the genes controlling wing length (long or vestigial) and abdomen width (broad or narrow) are linked on the same chromosome. Genotype and Phenotype Let's consider a cross between two Drosophila flies: Parent 1: Long wing (L) and broad abdomen (B) Parent 2: Vestigial wing (l) and narrow abdomen (b) The possible genotypes and phenotypes of the offspring are: LL or Ll: Long wing and broad abdomen ll: Vestigial wing and narrow abdomen Linkage and Recombination Since the genes are linked, the alleles for long wing and broad abdomen (L and B) tend to be inherited together, as do the alleles for vestigial wing and narrow abdomen (l and b). However, due to recombination during meiosis, some offspring may inherit a combination of alleles that are not linked, resulting in a recombinant phenotype. Calculation of Recombination Frequency By analyzing the offspring, we can calculate the recombination frequency, which is a measure of the distance between the linked genes. #GeneLinkage #Drosophila #Genetics #MolecularBiology #WingLength #AbdomenWidth #RecombinationFrequency #LinkageMap #GenotypeAndPhenotype #BiologyEducation #ScienceEducation #GeneticsEducation #DrosophilaMelanogaster #ModelOrganism
