What do you call an organism that possesses two dominant or two recessive genes fir a single trait?

I think you are referring to the term homozygous. This term applies not to the entire organism but is typically used with regard to one trait. For example, homozygous tall or homozygous dwarf when referring to height in peas. The term heterozygous refers to having one dominant and one recessive gene, or at least to having two different forms of the gene.

What do you call an organism with two dominant or two recessive gene's for a single trait?
Homozygous.
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.
When two or more forms of the gene for a single trait exist some forms may be?
dominant and others may be recessive.
Can several alleles affect a single trait?
When there are multiple alleles present for a trait a variety of phenotypical outcomes is possible. These traits can be dominant, recessive, co-dominant, or incompletely dominant.
What are the three types of dominance in modern gnetics?
The three types of dominance in modern genetics are, single gene inheritance, multifactual and mitochondrial. Other types are dominant and recessive genes.
What do you call an organism that possesses one dominant and one recessive genes for a single trait?
heterozygous
What do you call a organism that possesses one dominate and one recessive genes for a single trait?
heterozygous
What do you call an organism that possesses one dominate and one recessive genes for a single trait?
heterozygous
What do you call an organism with two dominant or two recessive gene's for a single trait?
Homozygous.
When both dominant and recessive alleles are present within a single nucleus the organism is for the trait?
You are supposed to have 2 alleles in a single nucleus and if not there can be a disorder i believe.
An organism with two different alleles for a single trait is said to be heterozygous?
A heterozygous is a hybrid of genes. It has a dominant and recessive gene. The dominant gene covers over the recessive trait, making the individual have the dominant trait. (trait are alleles...) or apex ans:two
Is turners recessive or dominant?
It is neither recessive nor dominant because it is a chromosomal disorder and not just a problem present in a single gene.
Is it possible to have a dominate recessive trait?
no, because dominant is different from recessive, its impossible to have a dominant-recessive trait because the dominant is when only one copy of the gene is present, while in the recessive a trait that must be contributed by both parents in order to appear in the offspring, in short the dominant is for single parent, while in the recessive is a product of two parents.
Dominant and recessive genes?
Dominant genes are shown for example as T recessive genes are shown as t if there is a dominant and recessive gene (Tt) then your child will get the dominant one this is called heterozygous. Meaning that they have two different genes for a trait such as curly hair and straight hair. There is also being homozygous (TT or tt) the only way your child could recieve a recessive gene such as left handednes, is if the two parents were carrying a recessive gene along with their dominant one or if they both were carrying two reccesive genes. the childs probable genotype can be explaind a lot better with a Punnet Square. I hope this wasn't too confusing.:-)
A single gene trait that has two alleles and that shows a simple dominant recessive pattern will result in?
A 3:1 phenotypic ratio (Mendelian inheritance).
What is a gene combination for a single trait?
homozygous dominant, heterozygous, or homozygous recessive
Why is an organism genotype may be homozygous dominant homozygous recessive or heterozygous but never heterozygous recessive?
