A homozygous condition would be the possession of alleles for red hair and red hair. A heterozygous condition would be characterized by the possession of alleles for brown hair and red hair.
It sounds like you are referring to homozygous vs heterozygous. If an organism has two identical alleles of the same gene, it is said to be homozygous. If an organism has two different alleles of the same gene, it is said to be heterozygous.If a homozygous organism has two identical dominantalleles, it is said to be homozygous dominant, while an organism with two identical recessive alleles is said to be homozygous recessive.If this was not what you're asking, please clarify your question on the discussion page so someone can improve this answer.
the organism that have two identical alleles would be called homozygous for that particular gene.
A sufferer of a genetic disorder would typically have two copies of a recessive allele (homozygous recessive) for that particular trait or condition. For dominant conditions, they would have at least one copy of the dominant allele (homozygous dominant or heterozygous). The specific alleles involved depend on the disorder in question.
To identify if a locus is homozygous or heterozygous, you would need to examine the alleles present at that particular locus. If both alleles are the same, then it is homozygous. If the alleles are different, then it is heterozygous. This can be determined through techniques like DNA sequencing or PCR.
Heterozygous
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
In genetics, homozygous genes are identical alleles, while heterozygous genes have different alleles. For example, TT(same alleles) is homozygous genotype, while Tt (different alleles) is a heterozygous genotype.
Yes.A homozygous genotype is a gene with two identical alleles. Recessive genes are represented by a lowercase letter. Thus, a homozygous recessive genotype would be two identical genes with lowercase letters.
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
homozygous = AA & AA Heterozygous = Aa
Actually, there aren't specific letters. The letters depend on the alleles. For example, if the alleles are A and a, then Aa would be heterozygous, since hetero means different. Homozygous, however, would be two of the same alleles, since homo means same. The homozygous would be AA or AA in this example. hope this helped!
Not necessarily. CC can be a homozygous genotype if both alleles are the same (for example, CC for a particular gene). However, CC can also represent a heterozygous genotype if it stands for two different alleles in a diploid organism (for example, Cc).
