Alleles are alternative forms of a gene, and they are responsible for differences in phenotypic expression of a given trait (e.g., brown eyes versus green eyes). A gene for which at least two alleles exist is said to be polymorphic. Instances in which...

Genes may often exist in more than one form, and these forms are termed alleles of the gene. Accordingly, an allele is one of at least two alternative forms of a particular gene. Alleles provide the genetic instructions for products that, although...

A fixed allele refers to a form of a gene (allele) carried by all members of a population at all loci for that particular gene. Accordingly, with regard to a fixed allele, all individuals within a population will be homozygous for that allele and no...

Allele is the shortened, and more commonly used, form of the word alleleomorph. An allele is one of a series of possible forms of a given gene. Different alleles differ in their sequence of DNA, this difference can be as small as only one base pair...

An allele (pronounced /əˈliːl/ (US), /ˈæliːl/ (UK)) is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus (position) on a chromosome. Usually alleles are sequences that code for a gene, but sometimes the term is used to refer...

ABSTRACT Extinction, recolonization, and local adaption are common in natural spatially structured populations. Understanding their effect upon genetic variation is important for systems such as genetically modified organism management or avoidance of drug resistance. Theoretical studies on the effect of extinction and recolonization...

Soybean [Glycine max (L.) Merr.] oil with elevated palmitate content may be useful for food and industrial applications requiring oil with high oxidative stability. The mutant line A30 with [approximately equals] 40 g [kg.sup.-1] greater palmitate content than conventional soybean oil was developed by...

Essay provides a description of multiple allele inheritance .
