What are domant traits?
Dominant traits are characteristics that manifest in an organism when at least one dominant allele is present in its genotype. In genetic terms, alleles are different versions of a gene, and dominant alleles overshadow the effects of recessive alleles. For example, if a trait is determined by two alleles, one dominant and one recessive, the dominant allele will determine the phenotype, or observable trait, even if the recessive allele is also present. This concept is a fundamental principle of Mendelian genetics.
When a organism has two different alleles coding for a single trait it is?
heterozygous. This means the organism has inherited two different versions of a gene that code for the same trait. One allele may be dominant and the other recessive, influencing the organism's phenotype.
Is co-dominant recessive?
No, codominance is a genetic relationship between two versions of a gene where both versions are expressed in the phenotype. In contrast, recessive traits are only expressed when an individual has two copies of the recessive allele.
What is a genotype composed of?
Genotype is the genetic make up of an organism both expressed (phenotype) and unexpressed.Example: AaeeDndn is the genotype which includes unexpressed (recessive) alleles a and dn.Expressed dominant traits A and Dn as well as expressed recessive traits (ee). Note that expressed recessive traits have to be homozygous.
What are the two different alleles for a gene?
I think it is Dominant and recessive.
An organism that receives two versions of a dominant trait?
dominant
Which versions of genes are dominant over others in genetic inheritance?
In genetic inheritance, dominant genes are versions of genes that are expressed over recessive genes. Dominant genes mask the effects of recessive genes when they are present together in an individual's genetic makeup.

Are sperm and egg cells in humans Have either all dominant or all recessive versions of genes?
The sperm and egg sex cells (or gametes) have both recessive and dominant genes in them.
Is co-dominant recessive?
No, codominance is a genetic relationship between two versions of a gene where both versions are expressed in the phenotype. In contrast, recessive traits are only expressed when an individual has two copies of the recessive allele.

What are individual versions of genes called?
Individual versions of genes are called alleles. Alleles are variations of a gene that can result in different traits or characteristics in an organism. Each individual inherits two alleles for each gene, one from each parent.
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.
What Alleles are considered?
Alleles are different versions of a gene that arise due to variations in the DNA sequence. They can be dominant or recessive, influencing traits expressed in an organism. For example, an allele for brown eyes may be dominant over an allele for blue eyes. In a diploid organism, each individual carries two alleles for each gene, one inherited from each parent.
What are alleles and what are the two forms?
Alleles are different versions of a gene that can code for different traits. The two forms of alleles are dominant and recessive. Dominant alleles mask the effects of recessive alleles when present together in an individual's genotype.
