Dominance or dominance – a form of relationship between alleles of one gene, in which one of them (dominant) suppresses (masks) the manifestation of the other (recessive) and thus determines the manifestation of the trait.
Complete dominance – with this variant of dominance, the heterozygous phenotype does not differ from the dominant homozygous phenotype for this allele.
Incomplete dominance – with it, heterozygotes have a phenotype intermediate between the phenotypes of dominant and recessive homozygotes.
Codomination – with this dominance in heterozygotes, the characters for which each of the alleles is responsible are manifested simultaneously and fully.
Overdomination is a stronger manifestation of a trait in a heterozygous individual than in any homozygous one.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
