Allele frequencies can change over time due to mutation, genetic drift, natural selection, and gene flow.
基因座频率会随时间变化,原因包括突变、遗传漂变、自然选择和基因流。
The concept of an
allele was introduced by Gregor Mendel in his study of genetics.
由孟德尔在他的遗传学研究中引入了基因座的概念。
In the context of population genetics, an
allele is one of several forms of a gene.
在群体遗传学的语境下,基因座是基因的几种形式之一。
Identical twins may have different
alleles for certain genes, leading to differences in their traits.
同卵双胞胎可能在某些基因上具有不同的基因座,导致他们的特征存在差异。
The presence or absence of certain
alleles can affect an individual's susceptibility to diseases.
某些基因座的存在或缺失会影响个体对疾病的易感性。
Alleles can be dominant or recessive, with the dominant
allele being expressed in the phenotype when present.
基因座可以是显性的也可以是隐性的,当显性基因座存在时,它会被表达在表型中。
The Human Genome Project aimed to identify all human
alleles and their locations on chromosomes.
人类基因组计划旨在识别所有的人类基因座及其在染色体上的位置。
Genetic testing can identify specific
alleles that increase the risk of developing certain genetic disorders.
遗传测试可以识别增加患某些遗传疾病风险的具体基因座。
Alleles can undergo recombination during meiosis, leading to new combinations of traits in offspring.
基因座可以在减数分裂过程中发生重组,导致后代出现新的特征组合。
The study of
allele frequency distributions across populations can provide insights into migration patterns and evolutionary history.
研究不同人群中的基因座频率分布可以提供关于迁徙模式和进化历史的见解。
