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 rain sleet and hail called?
Rain, sleet, and hail are all forms of precipitation. They occur when water vapor in the atmosphere condenses and falls to the ground in different forms based on atmospheric conditions.
Are the three known forms of uranium called copies of each other?
No, the three known forms of uranium - uranium-238, uranium-235, and uranium-234 - are isotopes of uranium with different numbers of neutrons. They have distinct nuclear properties that make them useful in various applications.
A vertical section of the ocean is called?
A vertical section of the ocean is called a water column, which includes different layers such as the epipelagic, mesopelagic, and bathypelagic zones. These layers are characterized by specific environmental conditions and support various marine life forms at different depths.
What is the record of earths history called?
The record of Earth's history is called the geological timescale. It is a classification system that organizes Earth's history into different time intervals based on significant geological events and changes in life forms.

Short Answer is - alleles.
What are different forms of a single gene called?
Different forms of a single gene are called alleles. Alleles can vary in sequence, resulting in different versions of a gene that may contribute to variations in traits among individuals.
