the different forms of the same gene" ("Definitions," 2010). How is an allele different from a gene? As a subcategory for characterizing genes, an allele is a type of
gene. It simply refers to the fact that the two members of a gene pair can produce "opposite contrasting phenotypes" (Basic Genetics, 2010). For example, in human beings, each individual
inherits their a gene from their mother and a gene from their father for each physical characteristic. But not all copies of a gene are identical and alternative forms of
a specific gene are referred to as alleles. Explain an example of a gene: Consider the gene for eye color. The woman has brown eyes (B), as does her
mother, but her father has blue eyes (b). Therefore, she is heterozygous for this trait (Basic Genetics, 2010). While her eyes are brown, due to the fact that brown is
the dominant gene, she also carries a recessive gene for blue eyes, which came from her father. Therefore, the genetic makeup for her eye color can be expressed Bb. Explain
an example of two alleles for that gene: When alleles are identical, the individual is homozygous for that trait. For example, if the woman marries a man who has blue
eyes, this indicates that he inherited a blue recess gene from both his mother and his father. When they have a child, the baby will receive a blue recessive gene
from the father, but can receive either a blue or brown allele from the mother, as she carries both. If her egg carries her mothers dominant allele for brown eyes,
the baby will have brown eyes; if the egg carries her fathers recessive gene for blue eyes, the baby will have blue eyes. As this indicates, recessive genes can
