Organisms that are homozygous dominant and those that are for a trait controlled by simple dominance have the same phenotype?

Because the dominant gene always appears in the phenotype, whether or not it is "pure" (homozygous) or "mixed" (heterozygous). The recessive gene does what it says: it is recessive to the dominant gene. So, if it comes between the two, the dominant always appears.
Of course, this only happens in your average Dominant-Recessive traits.

∙ 11y agothey are kinda like homozygous because they are so pretty lololo
OR
HETEROZYGOUS for a trait controlled by simple dominance have the same phenotype
Wiki User
∙ 12y ago"Homozygous" means that a trait contains either both dominant alleles or both recessive alleles of a gene. Thus, the trait can be either dominant or recessive.
The phenotype and genotype of an organism depends on whether the trait is homozygous dominant or homozygous recessive.

∙ 14y agobecause the phenotype of a heterozygous organism can be either A or B.

What is similar because the heterozygous phenotype is different from the homozygous dominant phenotype?
incomplete dominance
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
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.
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
Assuming there is no co-dominance or partial dominance, the result would be that 100% of the offspring would be blue, heterozygous flowers with the phenotype Bb.
What describes organisms or genotypes that are homozygous for a specific trait that always produce offspring of the same phenotype?
Yes, homozygous with homozygous (both the same genotype) will produce homozygous of the same genotype
Is it easier to analyze genotype by observing phenotype in organisms with complete dominance or in organisms with incomplete dominance?
It is easier to analyze genotype by observing phenotype in organisms with incomplete dominance (also known as codominance), because in incomplete dominance the individual will show a specific phenotype for each situation, whether it is homozygous dominant, heterozygous, or homozygous recessive. For example, in flowers, such as the ones that Mendel studied, a homozygous dominant flower will be red, a homozygous recessive flower will be white, and a heterozygous flower will be pink. In complete dominance, a heterozygous will only express the dominant phenotype, as opposed to incomplete dominance, in which a heterozygous individual will express a phenotype that is representative of both of the dominant and recessive traits. Because heterozygous individuals in complete dominance express the dominant phenotype, it is hard to determine whether the genotype is homozygous dominant or heterozygous for the trait. Hope this helps!
What is similar because the heterozygous phenotype is different from the homozygous dominant phenotype?
incomplete dominance
How is phenotype expressed in a incomplete dominance?
It's expressed when a heterozygous phenotype is between two homozygous phenotypes.
How many alleles influence a phenotype in incomplete dominance?
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. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.
And are similar because the heterozygous phenotype is different from the homozygous dominant?
Condominance and Incomplete Dominance.
How is incomplete dominance expressed in phenotype?
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
What and what Are similar because the heterozygous phenotype is different from the homozygous dominant phenotpe?
Incomplete Dominance and Codominance.
Condition that exists when the heterozygous phenotype is somewhere in between the two homozygous phenotypes?
Incomplete dominance
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 are codominant alleles and incompletely dominant similar?
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
Assuming there is no co-dominance or partial dominance, the result would be that 100% of the offspring would be blue, heterozygous flowers with the phenotype Bb.
What describes organisms or genotypes that are homozygous for a specific trait that always produce offspring of the same phenotype?
Yes, homozygous with homozygous (both the same genotype) will produce homozygous of the same genotype
