What else can I help you with?
How would you describe the alleles in a heterozygous genotype?
In a heterozygous genotype, an individual possesses two different alleles for a particular gene, with one being dominant and the other recessive. The dominant allele is expressed in the phenotype, while the recessive allele is not unless two recessive alleles are present.
When are both alleles expressed in offspring?
Both alleles are expressed in offspring when neither allele is dominant over the other, resulting in co-dominance. This means that both alleles are simultaneously expressed in the offspring's phenotype.
What are cells that contain two different alleles for a gene one dominant and one recessive?
Heterozygous cells contain two different alleles for a gene, typically with one allele being dominant and the other recessive. This means that the dominant allele will be expressed in the phenotype, while the recessive allele is present but not expressed.
What is expressed when neither copy of an allele completely masks expression of the other but instead a bending of alleles is seen?
incomplete dominance
When one allele shows dominance over another allele?
In cases of complete dominance, one allele, known as the dominant allele, masks the expression of the other allele, known as the recessive allele, in the heterozygous state. This results in only the dominant allele being expressed in the phenotype.
When the alleles of a gene pair are expressed differently but neither is dominant to the other?
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed.

Recessive alleles may not be expressed because they are?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps
What are the pair of alleles for a trait and how do they determine the expression of that trait?
Alleles are pairs of genes that determine a specific trait in an organism. Each parent contributes one allele, and the combination of alleles determines how the trait is expressed. If the alleles are the same (homozygous), the trait will be expressed in a certain way. If the alleles are different (heterozygous), one allele may be dominant and determine the trait's expression, while the other may be recessive and not expressed.
When are both alleles expressed in offspring?
Both alleles are expressed in offspring when neither allele is dominant over the other, resulting in co-dominance. This means that both alleles are simultaneously expressed in the offspring's phenotype.
What is codominace mean?
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
What are cells that contain two different alleles for a gene one dominant and one recessive?
Heterozygous cells contain two different alleles for a gene, typically with one allele being dominant and the other recessive. This means that the dominant allele will be expressed in the phenotype, while the recessive allele is present but not expressed.
What is expressed when neither copy of an allele completely masks expression of the other but instead a bending of alleles is seen?
incomplete dominance
What is meaning of alleles?
An allele is the different forms of a gene. For example the gene for eye colour has the alleles; brown, blue, green etc. In every person there are two alleles for every gene but both alleles are not always the same. They can be dominant and recessive; dominant alleles are expressed no matter what other allele is present, recessive alleles require both alleles to be the recessive one to be expressed. E.g. say B is the allele for brown eyes and b is the allele for blue eyes. Brown is dominant therefore if someone had Bb or BB they'd have brown eyes and if they had bb their eyes would be blue.
Why do we call some alleles dominant?
because it dominates the phenotype
What is expressed when niether copy of allele completely masks expression of the other but instead a blending of alleles is seen?
dominance :) i think its dominance.
What results when one allele is not dominant over the other?
When one allele is not dominant over the other, both alleles contribute to the phenotype in a form of incomplete dominance or codominance. In incomplete dominance, the heterozygous individual displays a phenotype that is a blend of the two alleles. In codominance, both alleles are expressed independently, resulting in a phenotype that shows traits from both alleles.
