Alleles
Genes can have different forms, known as alleles, that produce variations in a specific trait. These alleles can be dominant or recessive, determining which form of the trait is expressed in an individual. Additionally, some alleles can be co-dominant or show incomplete dominance, leading to unique phenotypic outcomes.
When two or more forms of a gene for a single trait exist, some forms of the gene may be dominant, while others may be recessive. Dominant alleles can mask the expression of recessive alleles in a heterozygous individual. This variation leads to different phenotypes depending on the combination of alleles an organism possesses.

When two or more forms of the gene for a single trait exist, some forms of the gene may be dominant, while others may be recessive. The dominant allele can mask the expression of the recessive allele in a heterozygous individual. This variation in alleles leads to different phenotypes being expressed in the organism.
A gene can have multiple forms, which are called Alleles. While a single gene may code for a trait in an organism, when multiple alleles exist for that gene, each different may produce a different character of that trait. For example, a person has two copies of the gene that codes for ABO blood type. There are three different alleles for this gene, A, B and O. This results in six different combinations of the alleles that the person can have (the genotype), which in turn results in four expressions of the gene in the person (called the phenotype), which is the blood type of the person.
When two or more forms of a gene for a single trait exist, some forms may be dominant and others recessive. Dominant forms of a gene will be expressed over recessive forms in the phenotype. This is known as codominance or incomplete dominance.

The different forms of a gene for a specific trait, such as height, are called alleles. These alleles can vary in terms of their specific DNA sequences, ultimately resulting in different phenotypic expressions of the trait. For example, in the case of height, an individual may inherit alleles for tall or short height from their parents, leading to variation in their own height.
