Dominance that occurs whenever the hybrid genotype produces a new intermediate phenotype?

∙ 12y ago
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.

Incomplete dominance occurs when the heterozygous genotype produces a phenotype that is a blend of the two alleles. This results in an intermediate phenotype that is distinct from the phenotypes of both homozygous genotypes.

Which is an example of imcomplete dominance?
An example of incomplete dominance is when crossing a red flower with a white flower produces pink flowers in the offspring, rather than a blend of the two parent colors. This occurs when the heterozygous genotype results in an intermediate phenotype that is different from either homozygous genotype.
What phenotype is produced by AA genotype?
The AA genotype typically produces the phenotype associated with the dominant allele A. This means that the dominant trait will be expressed in the individual with this genotype.
How does codominance work and why does it happen?
Incomplete dominance occurs when a homozygous genotype produces an intermediate, or middle phase before the result. This intermediate is the heterozygous' phenotype.
The term true-breeding strain refers to a genotype?
True-breeding strain refers to a genotype that, when self-pollinated or crossed with another organism with the same genotype, always produces offspring with the same phenotype. This means that the trait is homozygous and will be consistently expressed in the offspring generation after generation.
What is the origin of nondisjunction for an XXX genotype that produces a phenotype of a nearly normal female?
Nondisjunction in an XXX genotype can occur during cell division, leading to an extra X chromosome being present. In this case, the individual will have three X chromosomes instead of the usual two, resulting in a phenotype of a nearly normal female with some potential for developmental and reproductive issues.
What phenotype is produced by AA genotype?
The AA genotype typically produces the phenotype associated with the dominant allele A. This means that the dominant trait will be expressed in the individual with this genotype.
How is a snap dragon an example of incomplete dominance?
When they don't have pink as their color so the "parents" had to of been either both white or both pink. That is how you can tell when snapdragons are not following the pattern of complete dominance.
How does codominance work and why does it happen?
Incomplete dominance occurs when a homozygous genotype produces an intermediate, or middle phase before the result. This intermediate is the heterozygous' phenotype.
What does the term incomplete dominance refer to?
Incomplete dominance refers to a genetic scenario where neither allele is completely dominant over the other, resulting in a blending of the traits of the two alleles. This leads to an intermediate phenotype in individuals that inherit one copy of each allele.
A cross between a snapdragon with red flowers and one with white flowers produces a snapdragon with pink flowers The trait for flower color exhibits?
Incomplete dominance. Incomplete dominance occurs when the heterozygous condition results in a phenotype that is intermediate between the two homozygous conditions. In this case, the red and white flower colors mix to produce pink in the offspring.
What occurs when 50 percent of a protein produces a different phenotype than that produced by 100 percent or 0 percent of the protein?
incomplete dominance
The term true-breeding strain refers to a genotype?
True-breeding strain refers to a genotype that, when self-pollinated or crossed with another organism with the same genotype, always produces offspring with the same phenotype. This means that the trait is homozygous and will be consistently expressed in the offspring generation after generation.
Does meiosis produces phenotype cells?
Yes, meiosis produces phenotype cells.
What is the origin of nondisjunction for an XXX genotype that produces a phenotype of a nearly normal female?
Nondisjunction in an XXX genotype can occur during cell division, leading to an extra X chromosome being present. In this case, the individual will have three X chromosomes instead of the usual two, resulting in a phenotype of a nearly normal female with some potential for developmental and reproductive issues.
In incomplete dominance genotypes can be expected to appear in a ratio of?
1:2:1, as incomplete dominance results in a blending of traits from two different alleles, producing an intermediate phenotype in heterozygous individuals. This ratio is characteristic of crosses involving incomplete dominance.
Explain the difference between intermediate inheritance and codominance?
Intermediate inheritance refers to a situation in genetics where the heterozygous phenotype is a blend of the two homozygous phenotypes, such as in the case of flower color in snapdragons. Codominance, on the other hand, is a situation where both alleles of a gene are expressed fully in the heterozygous individual, resulting in a phenotype that shows traits of both alleles simultaneously, like in the case of human blood types.
Why is it difficult to determine the genotype of an organism that has a dominant phenotype?
It is difficult to determine the genotype of an organism with a dominant phenotype because the dominant phenotype masks the expression of the recessive allele. As a result, it is not possible to determine if the organism is homozygous dominant or heterozygous for that trait without further genetic testing or analysis.
