If one parent had 2 dominant genes then all offspring would have dominant phenotype, the same goes for both parents having dominant genes.

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?
The genotype of offspring that do not share the parents' phenotype would depend on the specific genetic makeup of the parents. In cases where the offspring do not exhibit the same phenotype as the parents, it is likely due to inheriting different combinations of alleles that result in a different expression of traits. This could involve the presence of recessive alleles or genetic variations that influence the phenotype differently than expected based on the parents' genotypes.
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.
Is chromosomal mutation dominant or recessive?
Chromosomal mutations can be either dominant or recessive, depending on the specific mutation and how it affects the expression of genes on the altered chromosome. Some chromosomal mutations can lead to a dominant phenotype if they result in the duplication or gain of genetic material, while others can lead to a recessive phenotype if they result in the loss or deletion of genetic material.
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 pattern is known as complete dominance, where the dominant allele masks the expression of the recessive allele in heterozygous individuals. As a result, individuals with one dominant and one recessive allele will display the same phenotype as individuals with two dominant alleles.
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 result of a cross between an individual who is homozygous dominant and another who is homozygous recessive for a trait?
The offspring will all be heterozygous for the trait, carrying one dominant and one recessive allele. This is known as a monohybrid cross, resulting in all offspring displaying the dominant trait phenotypically but carrying the recessive allele genotypically.
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?
The genotype of offspring that do not share the parents' phenotype would depend on the specific genetic makeup of the parents. In cases where the offspring do not exhibit the same phenotype as the parents, it is likely due to inheriting different combinations of alleles that result in a different expression of traits. This could involve the presence of recessive alleles or genetic variations that influence the phenotype differently than expected based on the parents' genotypes.
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.
