WebMar 15, 2024 · The main gene responsible for freckles is called MC1R. It comes in two different versions, freckle (F) and non-freckle (f). Like most other genes, we each have two copies of MC1R. Whether or not you have freckles depends on the combination of the freckle (F) and non-freckle (f) versions of MC1R you have. WebWith no dominant alleles, more phenotypes are possible, and the phenotype probabilities match the genotype probabilities. A simpler pattern arises when one of the parents is homozygous for all traits. In this case, the alleles contributed by the heterozygous parent drives all of the variability.
