Codominance is a form of inheritance wherein the alleles of a gene pair in a heterozygote are fully expressed.
What is it called when both alleles are expressed?
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. … In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed.
What is it called when both traits are expressed in a heterozygote?
Codominance happens when the two alleles are represented at the same time. They don’t blend together, though. Both traits are equally expressed. An example of codominance is the AB blood type.
How do you explain a recessive allele?
A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. In a dominant/recessive relationship between two alleles, the recessive allele’s effects are masked by the more dramatic effects of the dominant allele.
Which allele is always written first?
The alleles are represented by letters. The letter chosen is usually the first letter of the trait.
