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 ... WebMay 13, 2024 · What Is Simple Inheritance? Simple (or Mendelian) inheritance refers to the inheritance of traits controlled by a single gene with two alleles, one of which may be completely dominant to the other. The pattern of inheritance of simple traits depends on whether the traits are controlled by genes on autosomes or by genes on sex chromosomes.

Because avoiding bitter … WebExplanation: Freckles on the skin are controlled by a single gene on an autosome. There are two alleles for this gene: F (dominant) and f (recessive). Freckled skin is dominant to nonfreckled skin. Genotype FF or Ff results in freckled skin, while genotype ff results in nonfreckled skin.
