What Hair Color Is Dominant And Recessive. You can think of recessive alleles as t shirts and dominant ones as jackets. If your cousin received both recessive genes for light hair then it would be possible for the effects of the red hair gene to be visible.
Dark hair is dominant but your aunt and uncle are likely heterozygous for dark hair with one dominant dark hair gene and one recessive light hair gene. Therefore the curly hair gene is dominant and straight hair gene is recessive. From eye color to hair color to dimples dominant and recessive genes determine much of how a person is built.
Although hair color is dependant on dominant and recessive qualities predicting hair color is more complex than predicting other genetic traits.
The terms dominant and recessive when paired are commonly linked to science and genetics. You can think of recessive alleles as t shirts and dominant ones as jackets.
