Alleles and Genes

a gene that is found in one of two or more different forms in the same position in a chromosome, and so produces a particular characteristic that can be different for different people, such as eye colour

While an allele refers to a variant form of a gene, a gene is a broader term that refers to a unit of heredity in general. A gene is a sequence of DNA that contains the information to produce a specific protein or set of proteins, whereas alleles are the

Allele, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait. Learn more about alleles in

"Allele" is the word that we use to describe the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to lump the alleles into categories. Typically, we call them either normal o

Genesare sections of DNA that contribute to certain traits, characteristics or functions. Genes code for proteins or parts of proteins that influence things like the immune system, skin pigmentation, hormone production, and eye color. Genes are transcribe

Genes define the traits of an organism, while alleles are the alternative versions of those genes, determining the specific expressions of the traits.

等位基因 （allele）舊稱 對偶基因[1]，是 同源染色體 內同一個 基因座 上的多種表現形式；其在 細胞 有絲分裂 時的兩個染色體上的基因座是對應排列的，故細胞遺傳學裡稱其為等位。
