What is heterozygous dominate?
When you’re heterozygous for a specific gene, it means you have two different versions of that gene. The dominant form can completely mask the recessive one, or they can blend together. In some cases, both versions appear at the same time. The two different genes can interact in various ways.
How does codominance occur?
Codominance occurs when both alleles show dominance, as in the case of the AB blood type (IA IB) in humans. … In these cases, individuals with the same allele combination can produce different degrees of a phenotype in different individuals.
What does codominance mean in genetics quizlet?
Codominance. A condition in which both alleles for a gene are fully expressed.
What is codominance answer?
Answer: Codominance develops when there are two versions (alleles) of the same gene in a living being and both are expressed. Instead of being dominant on one trait over the other, both traits occur. In plants and animals with more than one pigment colour, codominance is easy to detect.
What is heterozygous dominant example?
One such example is brown eyes (which is dominant) and blue eyes (which is recessive). If the alleles are heterozygous, the dominant allele would express itself over the recessive allele, resulting in brown eyes.
What genotypes are heterozygous dominant?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.
