En allel kan nedarves enten dominant eller være recessiv. Derforuden findes to varianter af dominans, som kaldes co-dominans og ufuldstændig dominans . Allelen er dominant hvis den bestemmer det fænotypiske udtryk, mens den er recessiv, hvis den kan skjules bag en dominant allel og dermed kun udtrykkes, idet to ens recessive alleler forekommer samtidigt (såkaldt homozygoti ).

2020-05-08 · A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. When a dominant allele is completely dominant over another allele , the other allele is known as recessive .

In heterozygous relationships where neither allele is dominant but both are completely expressed, the alleles are considered to be co-dominant. Co-dominance is exemplified in AB blood type inheritance. A dominant allele is the type of allele that is expressed when it is present in either or both of the two chromosomes in the pair for a specific gene. dominant (Middle French (ca. 1400-1600)) 6.

(HPO, OMIM, Orphanet) Autosomal dominant inheritance In incomplete dominance, the effect of the allele is partial. While in Codominance, both the alleles expresses fully, creating a mixture of effects in phenotype.

Alleles that need only be present in one copy in an organism to be fatal are referred to as dominant lethal alleles. These alleles are not commonly found in populations because they usually result in the death of an organism before it can transmit its lethal allele on to its offspring. Een genetische eigenschap is dominant aanwezig als bij een diploïd organisme slechts een van de twee allelen (kopieën) van een gen (òf die op het van de moeder afkomstige chromosoom òf die op het van de vader afkomstige chromosoom) tot uiting (expressie) komt.
