WebFeb 2, 2024 · In linkage, a variety of ratios are produced. In most breeding experiments involving linkage produces approximately equal numbers of parental phenotypes and a significant smaller number of recombinant phenotypes (new combination of characters) in equal numbers.
WebMap units are a measure of the tendency for crossovers to occur between two loci. Because genes that are farther apart will have a higher likelihood of crossovers, the higher the crossover frequency, the farther apart the genes are on the chromosome. Let’s apply this idea to our test cross data. Test cross data allows us to indirectly measure ... Web3. In Drosophila, b+ is the allele for normal body color and at the same gene b is the allele for black body color. A second gene controls wing shape. The shape can be either normal ( vg+) or vestigial ( vg ). A cross is made between a homozygous wild type fly and fly with black body and vestigial wings. The offspring were then mated to black ...
