Alleles are the different forms of a gene.
Alleles are corresponding pairs of genes located at specific positions in the chromosomes. Together, alleles determine the genotype. Alleles which determine some aspect of the phenotype, the physical appearance of an organism, are said to be coding alleles.
When both alleles in a pair are the same, the alleles are homozygous. If the alleles are different, they are heterozygous. In the case of homozygous alleles, the expression of phenotype is usually very straightforward. In heterozygous instances, however, the phenotype of the organism is determined by which allele is dominant, meaning that one allele overrides the other.
In the case of eye color in humans, if someone inherits a blue allele and a brown allele, his or her eyes will be brown, because brown is a dominant genetic trait, requiring only one allele for expression. However, if that person had a child with someone who also carried a blue allele and both parents passed the blue trait down, the child would have blue eyes. This explains why blue-eyed children sometimes randomly pop up in a brown-eyed family: because someone in the family's genetic history had blue eyes.

What are the different forms called in an element that has forms with different numbers of neautrons?
Atoms of the same element can have different numbers of neutrons; the different possible versions of each element are called isotopes. For example, the most common isotope of hydrogen has no neutrons at all; there's also a hydrogen isotope called deuterium, with one neutron, and another, tritium, with two neutrons.
What is the border between two different air masses?
a front
What are atoms of the same element thay have different atomic masses?
when you have two different forms of an atom with different masses, it's called an isotope of the atom.
Are the three known forms of uranium called copies of each other?
The three form of uranium (α, β, γ) are called allotropic forms.
Why are genes distinguished by bases but not by the sugar-phosphate backbone?
The base sequence is what makes one gene different from another. There are four bases which can be arranged in many different sequences. The sugar phosphate backbone is the same in all the genes. It is impossible to identify a gene by this.
What are two forms of gene called?
The two different molecular forms of a gene are called alleles.
What is name for diffent forms of a gene?
The different 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 do you call a different form or version of a gene?
The different forms of a gene are called alleles.
What is alternate form of a gene called?
The different forms of a gene are called alleles.
Different forms of a gene are called what?
Different forms of a gene are called alleles. Genes are the ones that influence the traits that will be inherited in the DNA.
What term is used for different forms of a gene?
Alternate forms of the same gene are called alleles.
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.
What are two forms of a gene called?
The two different molecular forms of a gene are called alleles.
What are the different forms of a gene are called what?
Short Answer is - alleles.
What are different forms of a single gene called?
alleles
Different forms of a gene?
the alternative form of a gene is called an "allele."
