How does an allele determine a genotype?

Answer 1

An allele is a different form of the same gene.

Alleles are often represented by upper and lower case letters. The upper case letters represent the dominant form while the lower case letters represent the recessive form.

The combination of alleles for any genetic make-up is known as an organism's genotype. There can be many different forms of genotypes, including

AA - Homozygous Dominant Aa - Heterozygous aa - Homozygous Recessive

The expression of a genotype is called the phenotype. Otherwise known as the physical traits of an organism.

An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. The combination of alleles an organism inherits from its parents determines its genotype.
