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 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.
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What are the different forms of genes?
Genes can exist in different forms or variations called alleles. Alleles are alternative versions of a gene that can lead to different traits or characteristics in an organism. For example, a gene that controls eye color may have alleles for blue, brown, or green eyes.
What are different types of genes called?
Different types of genes are called alleles, which are alternate forms of the same gene that can produce variations in a trait. Additionally, there are also different categories of genes such as regulatory genes, structural genes, and non-coding genes that play various roles in controlling different biological processes.
Different versions of the same gene are called?
Different versions of the same gene are called
What are different versions of the same gene called?
Different versions of the same gene are called alleles. Alleles can differ in their DNA sequence, resulting in variations in the traits they encode for. These variations can lead to differences in an organism's phenotype.
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.
Different forms of genes are called?
different form of genes are called allele
Alternative versions of genes are called?
alternative forms of a gene are called as alleles..
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What are matching sets of chromosomes called?
Matching sets of chromosomes are called homologous chromosomes. These chromosomes have the same genes in the same locations but may have different versions of those genes. Homologous chromosomes are inherited from each parent.
What are the different forms of genes?
Genes can exist in different forms or variations called alleles. Alleles are alternative versions of a gene that can lead to different traits or characteristics in an organism. For example, a gene that controls eye color may have alleles for blue, brown, or green eyes.
What does most genes come in alternate forms called?
Most genes come in alternate forms called alleles. Alleles are different versions of a gene that can produce variations in certain traits or characteristics. Each individual inherits one allele from each parent.
What are the different formes of genes called?
Alleles are forms of genes for a trait.
What are different types of genes called?
Different types of genes are called alleles, which are alternate forms of the same gene that can produce variations in a trait. Additionally, there are also different categories of genes such as regulatory genes, structural genes, and non-coding genes that play various roles in controlling different biological processes.
Different versions of the same gene are called?
Different versions of the same gene are called
1Normal human lung cells contain two copies of chromosome 3 Together these are called a pair of homologous chromosomes How are homologous chromosomes similar and how are they different from one ano?
Homologous chromosomes have all the same genes however they may have different alleles (versions) of those genes.
