How is a dominant allele represented
WebEach pair of letters represents the genotype of a single gene. dominance relationship of the alleles of a single gene must be investigated by the appropriate experimenal crosses. When a problem is assigned in a genetic course, genetics dominance relationships are often specified by the instructor. WebThe allele (version of the gene) for dark body color is dominant, which means that a moth possessing at least one such allele will have a dark body. To have a light body, the moth has to have both alleles for light body color. Figure 2 Dark and light phenotypes of the peppered moth on dark bark (right) and lichen covered (left) trees
