What will a heterozygote show when two alleles are codominant?
A heterozygote will show both phenotypes. For example, a tortoiseshell colored cat is heterozygous for black and orange coat color and it has both black and orange hairs in its coat. Refer to the following link for an illustration: http://www.great-pictures-of-cats.com/tortoiseshell-cats.html
What are the phenotypes of two dominant alleles?
If two alleles are dominant, the phenotypes will reflect the dominant traits associated with each allele. Both alleles will be expressed in the phenotype, resulting in a phenotype that shows the dominant characteristics of both alleles.
What is it called When the heterozygotes display two phenotypes at the same time?
This is known as codominance, where both alleles in a heterozygous individual are expressed equally and simultaneously, resulting in a unique phenotype that shows characteristics of both alleles.
What is Co-dominant Alleles?
Co-dominant alleles are two different versions of a gene that are both fully expressed in a heterozygous individual. This means that both alleles contribute to the phenotype of the organism. An example of co-dominant alleles in humans is the ABO blood group system, where A and B alleles are co-dominant to each other.
What is it called when the phenotypes of two alleles blend together?
When the phenotypes of two alleles blend together, it is referred to as incomplete dominance. In this genetic scenario, neither allele is completely dominant over the other, resulting in a phenotype that is a mixture of both traits. For example, when a red flower is crossed with a white flower, the offspring may exhibit a pink phenotype.

Is it possible for 2 alleles to produce four phenotypes?
Yes which ever of the two alleles is dominant, then the phenotype will take the one of the dominant. they can be codominant, so in that case, you might be able to produce 4 phenotypes. it depends if the two alleles create 4
What is Co-dominant Alleles?
Co-dominant alleles are two different versions of a gene that are both fully expressed in a heterozygous individual. This means that both alleles contribute to the phenotype of the organism. An example of co-dominant alleles in humans is the ABO blood group system, where A and B alleles are co-dominant to each other.
How are codominant alleles and incompletely dominant similar?
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
The outward expression of a gene?
The outward expression of a gene is determined by the alleles. Alleles come and pairs, and the pairings can be heterozygous or homozygous. For homozygous (both alleles are the same) phenotypes, the trait you see is the same as the alleles. For example, if both alleles are for a white flower, the flower will be white. There are different outcomes for heterozygous (one dominant allele, the other recessive) phenotypes. In complete dominance (the most common), the dominant allele is the the trait you see. For example, the flower has an allele for red (dominant) and white (recessive), it will be red because red is dominant to white. In incomplete dominance, the dominant allele is not strong enough to fully cut out the recessive so trait will be a mix of both. In the flower's case, it would be pink because white will be seen through the red. In codominance, both alleles are expressed just on different areas. The flower would have both red and white splotches.
What is the difference between codominance and multiple alleles?
Codominance occurs when both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that displays characteristics of both alleles, such as in blood type AB. Multiple alleles refer to the existence of more than two alternative forms of a gene within a population, allowing for a variety of genotypes and phenotypes, like the ABO blood group system where three alleles (A, B, O) determine blood type. While codominance describes the expression of alleles, multiple alleles describe the variety of alleles available for a trait.
What is a pair of nonidentical alleles affecting two phenotypes for a given trait are both expressed at same time in heterozygotes?
Codominance is when a pair of nonidentical alleles at a gene locus both affect the phenotype in heterozygotes, and therefore both alleles are expressed simultaneously. This results in the expression of a unique phenotype that is a combination of the traits associated with each allele.
How is co dominance and incomplete dominance similar?
Both co-dominance and incomplete dominance involve a situation where alleles do not follow the traditional dominant-recessive pattern of inheritance. In both cases, heterozygous individuals show a phenotype that is a blend of the two homozygous phenotypes. The main difference is that in co-dominance, both alleles are fully expressed, while in incomplete dominance, the phenotype is a mix of the two alleles.
How do you find possible phenotypes in offspring?
The possible genotypes and phenotypes of the offspring can be determined using a Punnett square, a grid that shows the possible combinations of alleles that can result at fertilisation. The Punnett square below shows the expected genotypes of the offspring of parent pea plants that both have the genotype Rr.
Dominance that occurs whenever the hybrid genotype produces a new intermediate phenotype?
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.
