Segregation
The two different molecular forms of a gene are called alleles.
Alleles
Two copies of a gene are called alleles. Alleles can be the same (homozygous) or different (heterozygous).
The process that separates the two alleles of a gene during gamete formation is called segregation. This occurs during meiosis when homologous chromosomes separate, resulting in each gamete containing only one allele of each gene.
A gene is said to have multiple alleles if it has more than two different forms or variants (alleles). This means there are more than two variations of the gene present in a population.
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
Each person has two alleles for an autosomal gene, one inherited from each parent. These two alleles together determine an individual's genotype for that gene.
the organism that have two identical alleles would be called homozygous for that particular gene.
The genotype of an individual with two different alleles for a specific gene is called heterozygous.
Homozygous
the alternative form of a gene is called an "allele."
