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.

∙ 9y agoIf an individual inherits both a dominant gene and a recessive gene for a trait, he or she will have the heterozygous genotype and the dominant phenotype, meaning that the dominant gene is expressed while the recessive is not.

∙ 10y agoA dominant allele (form of a gene) is expressed when an individual has the homozygous dominant genotype (e.g. BB), or the heterozygous genotype (e.g. Bb) for that trait. The recessive allele is expressed when an individual has the homozygous genotype (e.g. bb) for that trait.

Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
What gene won't display its trait in the prescience of a dominate trait?
The recessive form of a gene, called a recessive allele, will not be expressed in the presence of the dominant form of the gene, called a dominant allele.
When is a recessive allel expressed in offspring?
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
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 is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
What does recessive mean as it relates to genes?
Recessive, as in recessive genes, refers to an inherited characteristic or trait that is expressed only when two copies of the gene responsible for it are present.
What is is the principal of dominance?
One gene on a chromosome is expressed, while the other gene on the homologous chromosome, being recessive, is not expressed.
What are genes that are less likely to be expressed called?
A recessive gene
What gene won't display its trait in the prescience of a dominate trait?
The recessive form of a gene, called a recessive allele, will not be expressed in the presence of the dominant form of the gene, called a dominant allele.
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
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).
A gene whose code is not expressed unless a similar allele is present is called an?
recessive gene
A gene that is not expressed when paired with a dominant allele is called?
mutation.
When is a recessive allel expressed in offspring?
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
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).
Why are recessive alleles not always expressed as the phenotype?
recessive alleles get masked to show the difference in a dominant gene and a recessive gene. the dominate genes masks the recessive genes to show that the dominate gene is more dominate or more likely to be the outcome than the reccessive gene but the masked gene is not always recessive.
