What else can I help you with?
What percent of the offspring will display the recessive trait if parent 1Tt crosses with tt?
Crossing Yy x Yy yields YY, 2Yy, yy. Since Y is dominant over y, then YY and 2 Yy all result in the same phenotype. Therefore 3/4 of the offspring will resemble their parents.
If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
What is the genotype of the offspring that do not share the parents phenotype?
If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.
When offspring show a blend of the parents traits one allele is dominant over the other?
The results in the offspring hinge on the genetic make up of the parents. Each expressed trait is either the result of a dominant or recessive phenotype. The relative dominance or recessiveness of the alleles doesn't change only the rate at which they are expressed based on the allele present for each obseerved trait in the parents.
In each case where Mendel crossed plants the offspring displayed only one of the two traits seen in the parents. This observation supports which principle of genetics?
Mendel's observation that the offspring displayed only one of the two traits seen in the parents supports the principle of dominance. This principle states that in a heterozygous individual, one allele (the dominant one) can mask the expression of the other allele (the recessive one). As a result, only the dominant trait is expressed in the phenotype of the offspring.
A homozygous dominant black bear is mated with a recessive brown bear what phenotype will probably result in the offspring of the two bears?
Phenotype: Black Bear x Brown Bear Genotype: BB x bb Possible gametes: B B b b Possible B B crosses: b Bb Bb b Bb Bb Phenotype of offspring: Only Black bears
What percent of the offspring will display the recessive trait if parent 1Tt crosses with tt?
Crossing Yy x Yy yields YY, 2Yy, yy. Since Y is dominant over y, then YY and 2 Yy all result in the same phenotype. Therefore 3/4 of the offspring will resemble their parents.
If about 50 percent of the offspring have the dominant phenotype and 50 percent have the recessive phenotype what are the genotype of the parents?
If 50% of the offspring show the dominant phenotype and 50% show the recessive phenotype, it is likely that one parent is heterozygous (Aa) for the trait and the other parent is homozygous recessive (aa). This would result in a 1:1 ratio of offspring showing each phenotype.
Is Aa and AA a dominant phenotype?
Yes, both Aa and AA genotypes represent the dominant phenotype for a specific trait. The presence of at least one dominant allele (A) will result in the dominant phenotype being expressed.
When inheritance of a particular trait follows a pattern of what individuals that are heterozygous for the trait have the same phenotype or physical characteristic as individuals who are homozyg?
This type of inheritance represents alleles at the same locus where one is recessive to the other. The dominant phenotype occurs in all heterozygous offspring as well as the homozygous dominant offspring. This yields a 3:1 phenotype and a 1:2:1 genotype.
If a homozygous dominant is crossed with a homozygous recessive for a given trait the offspring will be?
The phenotype will show the dominant trait. All dominant traits mask recessive ones; If the genotype is heterozygous (One dominant and one recessive) the organism's phenotype will be dominant.
Offspring that result from crosses between parents with different traits?
genes
What is the genotype of the offspring that do not share the parents phenotype?
If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.
What is the result of a cross between an individual who is homozygous dominant and another who is homozygous recessive for a trait?
All the offspring will be heterozygous with a phenotype showing the dominant trait. Let the alleles be H (dominant) and h (recessive). All the gametes from the first individual will be H, and from the other, h. Thus all the offspring must be Hh.
What is the phenotype offspring plants?
The phenotype of offspring plants refers to their observable traits, such as their physical appearance, behavior, or other characteristics. These traits result from the interaction between the plant's genetic makeup (genotype) and environmental factors. Offspring plants may exhibit a combination of traits inherited from their parents, leading to variations in their phenotype.
What is the phenotype ratio of a cross between a heterozygous male and female?
The phenotype ratio will depend on the specific genetic traits being studied. In general, a cross between two heterozygous individuals is expected to result in a 3:1 phenotypic ratio, with three-quarters of the offspring displaying the dominant phenotype and one-quarter displaying the recessive phenotype.
When offspring show a blend of the parents traits one allele is dominant over the other?
The results in the offspring hinge on the genetic make up of the parents. Each expressed trait is either the result of a dominant or recessive phenotype. The relative dominance or recessiveness of the alleles doesn't change only the rate at which they are expressed based on the allele present for each obseerved trait in the parents.
