In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed

What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
Is an allele that produces a trait in the heterozygous condition recessive?
No. A recessive allele will not be expressed phenotypically in the heterozygous state. A recessive allele can only be expressed phenotypically in the homozygous state.
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
What type of allele masks the expression of the recessive allele and is therefore expressed in the heterozygous?
A dominant allele will mask the prsence of a recssive allele
What happens to the recessive allele in a heterozygous offspring?
The recessive allele is present, but not shown in complete dominance. This is because the dominant allele is completely dominant over the recessive allele, therefore it is shown, while the recessive allele is hidden.
What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
What is the type of allele that only effect the phenotype in the homozygous chromosome?
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).
Is an allele that produces a trait in the heterozygous condition recessive?
No. A recessive allele will not be expressed phenotypically in the heterozygous state. A recessive allele can only be expressed phenotypically in the homozygous state.
If an allele for a particular trait is not expressed at all when another allele for the trait is present the allele is?
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 makes a dominant allele different from recessive Allie?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
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
If an allele for a particular trait is NOT expressed at all when another allele for the trait is present the allele is .?
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 is it Dominant allele What is a recessive allele?
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
What makes a dominant allel different from?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
Can a individual carry a gene that is not expressed?
not usually, most books fit into the normal genres: mystery, fiction, nonfiction, adventure etc. I believe this person is referring to "genes," not "genres." To answer the question, then: yes, you can have genes that are not expressed. Recessive genes, for example, will not be expressed in heterozygous individuals; they will only be expressed in homozygous recessive individuals. For example; if you have the genotype Aa, the recessive gene - "a" - will not be expressed because the genotype contains a dominant allele, and the dominant allele will always be the one expressed. The only way that the "a" allele will be expressed is, again, if you are homozygous for that recessive gene (your genotype would be aa).
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
