In ____________ both dominant and recessive alleles lack their dominant and recessive relationships.
A.Incomplete dominance – Expression of new phenotypes in the progeny other than parents phenotypes is called Incomplete dominance. In this, mixing of parental phenotypes occurs. Both phenotypes are expressed are partially.
B.Polygenic inheritance - Inheritance is controlled by two or more genes in which the dominant alleles have cumulative effect, with each dominant allele expressing a part of functional polypeptide and full trait is shown when all the dominant alleles are present, is called Polygenic or Quantitative inheritance.
C.Multiple alleles - Presence of more than two alleles for a gene is called Multiple alleles.
D.Codiminance - Expression of phenotypes of both parents in heterozygous condition is called codominance. In this, no existence of dominant and recessive traits.
So, the correct option is ‘Codominance’.
