The genotype of a person with one dominate allele for a gene and one recessive would be expressed as Aa or Yy. You can use any letter you would like except one will be shown as a capital (dominate) and one as a lower case (recessive). This combination is heterozygous for that trait.
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).
If the cat is suspected to be heterozygous for a recessive trait, the presumed genotype would be Aa, where A represents the dominant allele and a represents the recessive allele. This means the cat has one dominant allele and one recessive allele for the trait in question. The test cross would involve crossing this cat with a homozygous recessive individual to determine the genotype of the cat.
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
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.
Genotype Cc refers to the genetic make-up of an individual who has one dominant allele (C) and one recessive allele (c) for a particular gene. This means that the individual carries both the dominant and recessive traits for that gene, where the dominant trait (C) will be expressed in the phenotype.
In genetics, a plan with one dominant and one recessive gene can be described by a heterozygous genotype, such as Aa, where "A" represents the dominant allele and "a" represents the recessive allele. The dominant gene will express its trait in the phenotype, overshadowing the recessive gene. For example, if "A" codes for purple flowers and "a" for white flowers, a plant with the genotype Aa will have purple flowers. This illustrates how dominant traits can mask the presence of recessive traits in an organism.
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).
An organism with one dominant and one recessive gene for a particular trait is said to be heterozygous for that trait. The dominant gene will typically mask the expression of the recessive gene, resulting in the dominant phenotype being expressed. For example, if "A" represents a dominant allele and "a" represents a recessive allele, the heterozygous genotype "Aa" will display the trait associated with "A."
heterozygous recessive
If the cat is suspected to be heterozygous for a recessive trait, the presumed genotype would be Aa, where A represents the dominant allele and a represents the recessive allele. This means the cat has one dominant allele and one recessive allele for the trait in question. The test cross would involve crossing this cat with a homozygous recessive individual to determine the genotype of the cat.
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
In some but not all cases a dominant gene is a functional version (allele) of that gene while a recessive gene is a nonfunctional (or less functional) version (allele) of that gene. As the dominant gene produces a fully normally functioning protein if it is inherited in even just one copy that protein will "dominate" over the protein produced (if any is produced) by the recessive gene. Sometimes there are multiple different dominant alleles and/or multiple different recessive alleles of a specific gene (e.g. human blood types have 2 dominant alleles: A and B that produce different antigen proteins and 1 recessive allele: O that produces no antigen protein).
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
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.
A heterozygous genotype represents having two different alleles for a particular gene, with one being dominant and the other recessive. This results in the individual expressing the dominant trait while also carrying the recessive allele.
Genotype Cc refers to the genetic make-up of an individual who has one dominant allele (C) and one recessive allele (c) for a particular gene. This means that the individual carries both the dominant and recessive traits for that gene, where the dominant trait (C) will be expressed in the phenotype.
A plant that exhibits this genetic inheritance pattern would have a heterozygous genotype, where one allele is dominant and the other two alleles are recessive. This would result in the dominant trait being expressed in the plant's phenotype.
