What are the letters for homozygous dominant heterozygous and homozygous recessive?

∙ 14y ago
homozygous dominant means two alleles that are the same that are capital letters, heterozygous recessive means that to alleles are different BUT the same letters in lower case.
(alleles for gender)
EX:
TT, Tt is homozygous dominant
tt, tt is heterozgous recessive

Is AA a homozygous genotype?
homozygous = AA & AA Heterozygous = Aa
What type of letter do you use to represent a dominant trait?
Capital letter such as R for dominant and r for recessive trait
How do you represent alleles?
Alleles are represented as: Gg Where G is the dominant trait and g is the recessive trait Therefore, homozygous dominant would be: GG Homozygous recessive would be: gg and heterozygous would be Gg
Homozygous dominant homozygous recessive?
Gg G=dominant trait g=recessive trait
A dominant phenotype will only be expressed if the individual is homozygous dominant for that trait?
Well actually not necessarily. An individual can be homozygous or heterozygous dominant for a trait. As long as they have that dominant allele in that specific genetic trait, they will automatically express the dominant phenotype. If a person is homozygous dominant, it just means that they will pass on both dominant traits to the offspring. If a person is heterozygous dominant , it means that they will pass on both a dominant and recessive trait to their offspring.Hope that helps ! =D
How do genetics represent h dominant and Recessive allele?
A dominant genotype is represented as DD or Dd but with many different letters. The DD is a homozygous dominant, while the Dd is the heterozygous dominant. Recessive is always represented as dd or rr or whatever letter you want to use. It is always homozygous recessive. There can never be a heterozygous recessive.

Why is an organism genotype may be homozygous dominant homozygous recessive or heterozygous but never heterozygous recessive?
I take it you're referring to the phenotype. Say a trait, like flower colour, is influenced by a single gene. The plant will possess two copies of the gene, one from each parent, but only one colour is expressed. Let's say that red is dominant and white is recessive. A plant containing 2 red alleles (homozygous for the dominant allele) will be red. A plant containing 2 copies of the white allele (Homozygous recessive) will be white and heterozygous plant, containing a single copy of both alleles will be red. There is no heterozygous recessive because the dominant allele will determine the phenotype.
How do you represent alleles?
Alleles are represented as: Gg Where G is the dominant trait and g is the recessive trait Therefore, homozygous dominant would be: GG Homozygous recessive would be: gg and heterozygous would be Gg
Homozygous dominant homozygous recessive?
Gg G=dominant trait g=recessive trait
What is a homozygous dominant?
Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes. It is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.

Which is a heterozygous or hydrid genotype?
A heterozygous genotype consists of a dominant gene and a recessive gene. Homozygous genotypes consist of two dominant genes (Homozygous Dominant) ro two recessive genes (Homozygous Recessive).Heterozygous: XxHomozygous: Dom. XXRec. xx
Is the trait TT heterozygous or homozygous?
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.
What offspring would you get if you cross a homozygous tall plant with a homozygous short plant?
Homozygous dominant would be all Capital letters. Homozygous recessive would be all lower case letters. So...in basic color genetics for horses: A homozygous recessive horse would be aaee A homozygous dominant horse would be AAEE
What is the difference between homozgous and heterozygous?
Heterozygous vs. Homozygous: These terms refer to genetic mutations. There are two copies of the protein codes in the genetic code. If one copy is normal and the other has the mutation, it is said to be heterozygous. If both copies have the mutation, it is said to be homozygous. For example: A/A -- homozygous. A/a -- heterozygous. a/A -- heterozygous. a/a -- homozygous.Homologous refers to the pair of chromosomes that are the same whilst Homozygous refers to the fact that alleles of a gene pair are the same
