Widow's peak is a dominant trait. This means that if a person inherits one copy of the gene for a widow's peak from either parent, they will have a widow's peak.
If purple flowers are dominant to white flowers, it means that a plant with one purple allele and one white allele will display the purple flower phenotype. The white flower phenotype would only be expressed if the plant inherits two white alleles.
Yes, dominant and recessive genes play a role in determining physical traits in offspring. Dominant genes are more likely to be expressed in the phenotype, while recessive genes are typically masked unless an individual inherits two copies of the recessive allele. This interplay between dominant and recessive genes contributes to the variety of physical characteristics seen in offspring.
That one gene expresses most or all of a trait over another variation of that gene ( recessive allele ) and in heterozygous condition, Aa. This does not mean the gene " dominates " as dwarfism is a dominant trait that is not greatly represented in the human populations gene pool

The traits inherited depends upon the alleles that have been passed on from the father and mother.The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed.For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele .TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait.In this case the dominant allele masks the recessive allele and the pea plant is still tall.tt - when there are two recessive alleles the pea plant will express the recessive trait and the pea plant is short.For a recessive trait to show up there should be a pair of recessive alleles.
Yes, Huntington's disease is autosomal dominant with high penetrance. Every individual who inherits the allele gets the disease.
A recessive gene or gene combination can be present in a generation without affecting the phenotype if it is masked by a dominant gene. This means that the trait associated with the recessive gene will only be expressed if an individual inherits two copies of the recessive gene.
Widow's peak is a dominant trait. This means that if a person inherits one copy of the gene for a widow's peak from either parent, they will have a widow's peak.
No, the dominant allele will be expressed in the individual's phenotype, masking the presence of the recessive allele. The recessive allele will only be expressed if an individual inherits two copies of the recessive allele.
Ok, im assuming your question is "if two recessive alleles are present will the trait be expressed" A trait will be expressed if two alleles are recessive but it will not be the same representation as two dominant alleles. For example, T being a tall pea plant and t being a small pea plant. Two recessive alleles or, homozygous recessive, alleles The other option would be there is one dominant and one recessive, heterozygous, which would look like Tt. This would take on the trait of the dominant allele usually expressed by the capital letter. So this heterozygous plant would be tall.
No, Yy is not a phenotype. Yy represents genotypes, specifically the alleles an individual inherits for a particular gene. Phenotypes are the physical characteristics or traits that result from the interaction of an organism's genotype with its environment.
If purple flowers are dominant to white flowers, it means that a plant with one purple allele and one white allele will display the purple flower phenotype. The white flower phenotype would only be expressed if the plant inherits two white alleles.
Yes, dominant and recessive genes play a role in determining physical traits in offspring. Dominant genes are more likely to be expressed in the phenotype, while recessive genes are typically masked unless an individual inherits two copies of the recessive allele. This interplay between dominant and recessive genes contributes to the variety of physical characteristics seen in offspring.
An allele can effect the phenotype of an organism by its dominance or recessiveness. If two dominant alleles are crossed the offsprings will carry the dominant trait of the alleles. If a dominant allele is crossed with recessive allele the phenotype of the offsprings will be of that of the dominant allele. And if two recessive alleles are crossed the phenotype of their offsprings will carry the reccesive trait.
Mid-digital hair is considered a dominant genetic trait. This means that if an individual inherits the allele for mid-digital hair from either parent, they will exhibit the trait.
