It is called CODOMINANCE if the alleles each express when the phenotype is heterozygous.
Let's look at the following situation. There are snapdragon flowers that are homozygous (having 2 of the same allele) for red. Let's call them R. There are also snapdragon flowers that are homozygous for white. Let's call them r. If you take one of the RR flowers and breed it with a rr flower, you will get Rr.
If one of the alleles is dominant, then the flower will be the color of the dominant allele. If R (red) is the dominant allele, then all of the offspring will be red; if r (white) is the dominant allele, then they will be white. However, if they are codominant, then if the genotype is heterozygous (Rr), then the alleles will both express- in this case, the offspring would be pink.
Hope I helped!
When an allele is neither dominant nor recessive, it means that both alleles equally influence the trait. This is known as codominance, where both alleles are expressed in the phenotype of the individual.
If neither are Dominant Or Recessive then its called co dominance or spuedo - dominance
codominance
Actually a chromosome consists of many genes/alleles and is neither recessive or dominant in and of itself.
Incomplete dominant alleles.
Incomplete Dominance.
Codominace
this is called codominance
Alleles can be dominant or recessive
Both of the alleles must be recessive. The trait expressed is a recessive trait.
codominace
Both of the alleles must be recessive. The trait expressed is a recessive trait.
