You can see why the allele for brown eyes is therefore dominant – if you only have 1 copy of the allele, melanin will still be synthesized, and your eyes will appear brown. However, the allele for blue eyes must be recessive, because you will only have blue eyes if neither of your eye color alleles code for melanin production. 2019-08-21 · The dominant allele is expressed and the recessive allele is masked.

In this case, someone who expresses an X-linked dominant allele will exhibit the disorder and be considered affected. X-linked dominant traits do not necessarily affect males more than females (unlike X-linked recessive traits). The exact pattern of inheritance varies, depending on whether the father or the mother has the trait of interest. When two copies of a gene are present a dominant allele will result in the associated phenotype being expressed even when the dominant allele is only present on one copy of the chromosome. 2015-11-15 · Recessive allele is the allele that is masked by the dominant allele.

A gene that is recessive. Allel. En av två eller flera varianter av en viss gen. Olika alleler kan till exempel resultera i olika blodgrupper eller olika färger på en blommas kronblad.
