How is phenotype expressed in a incomplete dominance?
It's expressed when a heterozygous phenotype is between two homozygous phenotypes.
What occurs when the heterozygous condition exists as an intermediate between the two homozygotes?
When the heterozygous condition exists as an intermediate between the two homozygotes, it is known as incomplete dominance. In this scenario, neither allele is dominant, resulting in a blending of the two traits. This leads to a phenotype that is a mix or intermediate of the two homozygous phenotypes.
When can you use a test cross?
A test cross is used to determine the genotype of an organism exhibiting a dominant phenotype. By crossing this organism with a homozygous recessive individual, the offspring's phenotypes reveal whether the dominant organism is homozygous or heterozygous. If any recessive phenotypes appear in the offspring, the dominant parent is heterozygous; if all offspring display the dominant phenotype, the parent is likely homozygous. This method is commonly employed in genetics to assess inheritance patterns.
What is the genotype and phenotype of homozygous?
Are you talking about phenotype or genotype? Phenotype is the expression of the genotype. Genotype is what you inherited. Phenotype is what you see. Homozygous is the same. Heterozygous is different. If you inherit one allele for blue eyes and one allele for brown eyes, your phenotype should be brown eyes. Your genotype would be brown eyes, blue eyes. You would have a heterozygous genotype.
When traits are inherited in an incomplete dominance pattern what is true about the phenotype of the heterozygotes?
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white.
How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
When a cross between a red flower and a white flower yeilds pink offspring the trait is?
Incomplete dominance, where the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes.
Heterozygus phenotypes show qualities of both alleles?
Yes, that's correct. Heterozygous individuals have two different alleles at a specific gene locus, and they can express traits from both alleles. This can result in a combination of traits or an intermediate phenotype that differs from either homozygous condition.
What is the phenotype of homozygous yellow grained corn and heterozygous yellow grained corn?
The phenotype (as I assume would be colour) for both homozygous and heterozygous yellow-grained corn is yellow.
How are codominant alleles and incompletely dominant similar?
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
What Alleles that display equal power in determining a phenotype?
Homozygous dominant and heterozygous both are a dominant phenotype.
If dad has freckles and is homozygous and mom has freckles and is heterozygous what phenotypes and genotypes can you expect their offspring?
Alright, I suppose I will do your homework for you.. Here is your punnet square: F F F FF FF f Ff ff Therefore, 3/4, or 75%, offspring will have the phenotype of having freckles, and 1/4, or 25% will have the phenotype of no freckles. And 2/4, or 50%, of the offspring will have the genotype for homozygous for freckles, 1/4, or 25%, of the offspring will carry a heterozygous trait for freckles, and 1/4, or 25%, of the offspring will have the phenotype for homozygous no freckles.
