There are 23 pairs of chromosomes<\/a> in each human cell and hundreds of thousands of distinct genes on each chromosome.<\/p>\n\n\n\n

An individual inherits two versions of each gene, known as alleles, from each parent.<\/p>\n\n\n\n

An allele is a chromosomal pair of genes that controls a heritable trait.<\/p>\n\n\n\n

Alleles can be categorized as dominant or recessive, where dominant refers to the visible trait, and recessive refers to the one that is not visible morphologically. <\/strong><\/p>\n\n\n\n

Dominant alleles are generally denoted by capital letters, whereas recessive alleles are denoted by lowercase letters.<\/strong><\/p>\n\n\n\n

\"Dominant
Dominant and Recessive Traits<\/figcaption><\/figure>\n\n\n\n

A homozygous trait has either two capital letters or two lowercase letters.<\/p>\n\n\n\n

Heterozygous traits are those that have alternating letters. The capital letter will always come first in heterozygous alleles.<\/p>\n\n\n\n

For example: <\/strong><\/p>\n\n\n\n

If the dominant gene for brown eyes is \u201cB\u201d<\/strong> and the recessive gene is \u201cb\u201d<\/strong> for blue eyes, then the alleles for the dominant trait can be either \u201cBB\u201d<\/strong> or \u201cBb\u201d<\/strong> while \u201cbb\u201d<\/strong> is for a recessive trait.<\/p>\n\n\n\n

A person will exhibit the dominant trait if they have a heterozygous set of alleles, i.e., BB or Bb.<\/p>\n\n\n\n

In the case of a recessive trait, the alleles of the trait-causing gene are the same, and both recessive alleles must be present to express the trait (bb). <\/p>\n\n\n\n

Having the same two copies of an allele is a homozygous condition.<\/p>\n\n\n\n

When only one copy is present, a recessive allele does not result in any trait. <\/p>\n\n\n\n

On the other hand, a dominant trait can also be expressed when one of the two alleles is present.<\/p>\n\n\n\n

Many genes interact in the production of one trait, such as hair color, eye color, size, shape, and so forth, and one gene (in conjunction with others) often influences many traits.<\/p>\n\n\n\n
