Freckles are a dominant trait. A heterozygous individual has one dominant allele (F) and one recessive allele (f). When two heterozygous individuals (Ff) mate, the possible genotypes for their children are FF, Ff, Ff, and ff. Thus, 75% will have freckles (FF or Ff) and 50% will be heterozygous (Ff).
