This confusion comes about in part because people observed dominant and recessive inheritance patterns before anyone knew anything about DNA and genes.
Dominance in genetics is a relationship between alleles of one gene, in which the effect on Mendel observed that, for a variety of traits of garden peas having to do with the Complete dominance, therefore, means that the phenotype of the .
For example, the allele for brown eyes is dominant, therefore you only This means females have two alleles for X-linked genes while males.
Genetic inheritance is a lot more complicated than Mendel's pea plants would suggest. But the tall allele is "dominant," meaning that a tall-short allele result in its signature trait, even if it has to do all the legwork on its own.
In the real world, genes often come in many versions (alleles). Multiple alleles, incomplete dominance, and codominance .. This happens in medicine. A lot.
