How Do You Spell ALLEL?

1. Allel is a term used in genetics to describe the alternative forms of a gene that can occupy a specific position, or locus, on a chromosome. These alternative forms are responsible for variations in traits among individuals. Alleles occur in pairs, with each parent contributing one allele to their offspring.

   Alleles can be either dominant or recessive, determining the expression of a trait. A dominant allele is one that is always expressed in the phenotype, or physical characteristics, of an individual, even if the corresponding recessive allele is present. On the other hand, a recessive allele remains hidden in the presence of a dominant allele and is only expressed when both alleles at a particular locus are recessive.

   Furthermore, alleles can be either homozygous or heterozygous. Homozygous alleles refer to a pair of identical alleles at a specific locus, either dominant (AA) or recessive (aa). Heterozygous alleles refer to a pair of different alleles at a specific locus, with one being dominant and the other recessive (Aa).

   Alleles play a crucial role in genetic inheritance and the diversity of traits observed in a population. They determine the inheritance patterns of genetic diseases, disorders, and other phenotypic variations. Understanding the concept of alleles is fundamental in unraveling the mechanisms behind genetic inheritance and the study of genetics as a whole.
