Which both alleles contribute to the phenotype of the organism?
Both the A and B alleles contribute to the phenotype of the heterozygote. Thus the alleles A and B are said to be co-dominant.
What is the phenotype of a heterozygous organism?
The genotype gives rise to the phenotype. Depending on the different relationships between alleles, different phenotypes are created in a heterozygous individual. In alleles that show complete dominance, the heterozygous phenotype will be the same as the dominant phenotype.
What does it mean if two alleles are heterozygous?
​Heterozygous = Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.
What is the phenotype of an individual heterozygous for both traits?
Codominance occurs when both alleles are expressed equally in the phenotype of the heterozygote.
Which of the following is a heterozygous dominant genotype?
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.
When both alleles are expressed in the phenotype this is called?
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.
When the heterozygous genotype results in a phenotype where both alleles are fully and separately?
Codominance occurs when two heterozygous alleles are fully expressed in the phenotype of an organism. The distinct phenotypes produced by each allele are expressed.
Why heterozygous genotype will have the dominant phenotype?
One allele can be dominant and mask the effect of a second recessive allele in a heterozygous organism that carries two different alleles at a specific locus. This means that the genotype of an organism with a dominant phenotype may be either homozygous or heterozygous for the dominant allele.
What happens to the phenotype of the heterozygotes?
Mendel observed that a heterozygote offspring can show the same phenotype as the parent homozygote, so he concluded that there were some traits that dominated over other inherited traits. However, the relationship of genotype to phenotype is rarely as simple as the dominant and recessive patterns described by Mendel.
Is heterozygous a genotype or phenotype?
An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
What happens to the phenotype of the heterozygotes when traits are inherited?
When both alleles are expressed in the heterozygous state?
When both alleles are expressed in heterozygous individuals this is called? Codominance. the relation between two alleles of a gene, such that both alleles are phenotypically expressed in heterozygous individuals.
