Allele - Wikipedia
网页An allele[1], or allelomorph, is a variant of the sequence of nucleotides at a particular location, or locus, on a DNA molecule. [2] Alleles can differ at a single position through single nucleotide polymorphisms (SNP), [3] but they can also have insertions and deletions of up to several thousand base pairs. [4]

Allelic heterogeneity - Wikipedia
网页Allelic heterogeneity is the phenomenon in which different mutations at the same locus lead to the same or very similar phenotypes. These allelic variations can arise as a result of natural selection processes, as a result of exogenous mutagens, genetic drift, …
科学网—注意区分gene和allele - 闫双勇的博文
网页2011年8月7日 · 等位基因间的互作（allelic interaction） 导致显隐性 (dominance) 的差别，而基因（座位）间的互作（gene interaction） 导致的是上位性 (epistasis)。 这是导致我们很多学生无法正确理解数量遗传学基本原理的主要原因，包括为什么表型相同的两个亲本也可以用来产生分离群体进行基因定位。 其实是没有区分 Aa 和 AAbb 的差异。 如果真要累加 favorable genes， 其意思是说，有些 gene 座位是有利的，有些基因座位本身是不利的， …
Allele | Definition, Examples, & Facts | Britannica
网页2024年8月26日 · 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. The combination of alleles that an organism carries constitutes its genotype.
Allele - National Human Genome Research Institute
网页4 天之前 · An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.
Bi-allelic and monoallelic expression | Learn Science at Scitable
网页The two chromosomal copies (alleles) of a gene are designated A and a. In most cases, both alleles are transcribed; this is known as bi-allelic expression (left). However, a minority of genes...
