alleles

alleles的音标是["æleɪz]，基本翻译是等位基因。速记技巧可以是：谐音记忆：“爱乐”→爱乐（等位基因）组合。

allele这个词源自拉丁语“allum”和“aleo”，意思是“小颗粒”或“碎片”。它的变化形式包括复数形式alleles，过去式和过去分词形式alitelized，现在分词形式alleling。

相关单词：

1. gene（基因）：与allele同源，它也源自拉丁语，表示“小颗粒”或“碎片”，是遗传信息的基本单位。

2. genotype（基因型）：表示一个生物体的基因组成，它是由一组特定的等位基因组成的。

3. phenotype（表型）：表示一个生物体的表现型，它是由环境和其他基因的影响下表现出来的特征。

4. heterozygote（杂合子）：表示一个生物体具有两个不同等位基因的个体，它在遗传学上是不纯合的。

5. homozygote（纯合子）：表示一个生物体具有两个相同等位基因的个体，它在遗传学上是纯合的。

以上这些单词都与遗传学和生物学的概念密切相关，并且反映了生物学中基因和遗传学的重要概念和过程。

Genetics and Genomics: Understanding Genetic Variation in Human Populations

Genetic variation plays a crucial role in human health and disease, and understanding this variation is essential for developing effective diagnostics, treatments, and preventions. One area of genetic research that has gained significant attention is the study of allelic variants, which refer to individual differences in genes that can affect an individual"s risk for diseases or traits. Understanding allelic frequencies, which are the relative amounts of different alleles present in a population, is crucial for identifying risk factors and developing targeted interventions. Additionally, allelic exchange, which involves swapping one allele for another, can be used to correct genetic defects or study gene function in greater detail. Understanding allelic disequilibrium, which refers to patterns of association between alleles and diseases or traits, can provide valuable insights into the genetic basis of diseases and traits. Furthermore, heterozygous allelic variation refers to individuals who possess one copy of a variant allele and one copy of the normal allele, and understanding this variation can provide valuable insights into disease risk and treatment options. Lastly, allelic imbalance refers to patterns of inheritance where one allele is preferentially inherited over another, and understanding this phenomenon can provide valuable insights into the development of certain diseases and traits. In conclusion, genetics and genomics are essential for understanding human health and disease, and understanding allelic variation is integral to this effort.
