Webb13 sep. 2024 · We’ve gotten a lot of questions recently about the relationship between DNA test results, and traits like blood type and eye color. The answer lies in the relationship between genotypes and phenotypes. Genotypes are the exact DNA — the A’s, T’s, G’s, and C’s — that you inherited from your parents. Phenotypes are the resulting ...

WebbEye colour and blood groups are both examples of dominant/recessive gene relationships. Eye colour. The allele for brown eyes (B) is dominant over the allele for blue eyes (b). So, if you have one allele for brown eyes and one allele for blue eyes (Bb), your eyes will be brown. (This is also the case if you have two alleles for brown eyes, BB.)
WebbRepresenting just 2% of the global population, green eyes are the absolute rarest of all eye colors.
