They are traits that are passed on from parent to offspring. There are also two types of alleles; Dominant and recessive.

The different forms a gene may have for a trait?
Alleles are the different forms that a gene may have for a certain trait. They used to be called allelomorphs.
Why you called co-dominance when a person possess two different alleles at the same locus and both alleles are expressed in the phenotype?
Both of the parent's alleles are either dominant or recessive.
A perlino horse has two cream alleles on what base color?

Does only the dominate male goat mate?
In humans, the inheritance of many traits, including blood type, is determined by multiple genes. The ABO blood group system is one such example. The ABO system is controlled by three alleles, which are alternative forms of the same gene, on chromosome 9. The three alleles are A, B, and O. Each person has two copies of the ABO gene, one inherited from each parent. The A and B alleles are codominant, meaning that if a person inherits both A and B alleles, they will express both A and B antigens on their red blood cells. The O allele is recessive, meaning that a person must inherit two copies of the O allele to express the O antigen. Because both the A and B alleles are codominant, neither is considered dominant over the other. Therefore, males do not carry the A allele as a dominant gene. Instead, they can inherit either the A or B allele from either parent, or they can inherit two copies of the O allele, which would result in the O blood type.

What is heterozygouz?
Many organisms contain two copies of each chromosome, and generally these two chromosomes are not identical. If a particular trait, such as the shape of a pea, is determined by one particular section of a chromosome, it is possible for the two copies of the chromosome to have different instructions for the trait. If the two sections of the two chromosomes have different instructions, this is called being heterozygous.Often if an organism is heterozygous for a trait, one of the sets of instructions (called an allele) will be dominant over the other. This means that if either of the chromosomes has that dominant version of the allele, that is the set of instructions that will be followed.Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r). A heterozygous plant would contain the following alleles for seed shape: (Rr).Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive. Using the previous example, round seed shape (R) is dominant and wrinkled seed shape (r) is recessive. Round: (RR) or (Rr), Wrinkled: (rr).
Two different forms of the same gene are called?
Alleles
What are two forms of a gene called?
The two different molecular forms of a gene are called alleles.
Two forms of the same genes are known as?
Different forms of the same gene are called alleles.The different forms of a gene are called alleles.
What are the two forms of genes called?
The two different molecular forms of a gene are called alleles.
What are two forms of gene called?
The two different molecular forms of a gene are called alleles.
What is the alternate form of a gene called?
Alleles are alternative forms of genes.
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What has two identical alleles for a trait?
A heterozygote is an organism with two different alleles for a trait.
Different forms of gene?
Alleles are the different types of genes.
What is multiple allele gene expression?
Instead of having only two alleles for a trait, there are more than two. An example in humans is the ABO blood group system, where there are three alleles that are possible. However, an individual can only inherit the alleles of his/her parents, for a total of two alleles.
What are contrasting forms of genes called?
Alleles
Organisms with two different alleles for a trait?
The organism that has two different alleles for the same trait is called heterozygous. This also refers to a cell or an individual that has two different forms of gene.
