Homozygous vs. Heterozygous: Definitions and Differences
2024年3月20日 · "Homozygous" and "heterozygous" describe the pairs of genes you inherited from your parents. If you are homozygous for a particular gene, it means you inherited the same version of that gene from both your mother and father.
Heterozygous - National Human Genome Research Institute
2 天之前 · Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker. By contrast, an individual who is homozygous for a marker has identical versions of that marker.

2024年8月25日 · Heterozygous is a term used in genetics to describe when two variations of a gene, known as alleles, are paired at the same location (locus) on a chromosome. By contrast, homozygous is when there are two copies of the same allele at the same locus.
Heterozygous - Definition and Examples | Biology Dictionary
2017年4月27日 · Heterozygous is a description of the genotype, or combination of alleles present in an organism. The genotype gives rise to the phenotype. Depending on the different relationships between alleles, different phenotypes are created in a heterozygous individual.
Heterozygous: Definition, Examples, and Comparison to …
2020年1月7日 · If you’re heterozygous for a dominant disorder, you have a higher risk of developing it. On the other hand, if you’re heterozygous for a recessive mutation, you won’t get it.
Understand the Meaning of Heterozygous - ThoughtCo
2019年11月27日 · In diploid organisms, a mutation that occurs on only one allele for a gene is called a heterozygous mutation. Identical mutations that occur on both alleles of the same gene are called homozygous mutations. Compound heterozygous mutations occur as a result of different mutations that happen on both alleles for the same gene.
一叶知因丨基因科普之Heterozygous ＆ Homozygous - 健康界
2021年3月4日 · 在遗传学中，你的某些特质（比如基因）会决定你的某些特征，你可以从你的父母那里分别得到这些特质的一部分。 你可能有一个棕色眼睛的爸爸和一个蓝色的妈妈。 你的爸爸可能是BB或Bb基因型，你的妈妈可能是bb基因型。 就像眼睛的颜色一样，有棕色，蓝色，淡褐色和其他的颜色。 棕色眼睛（B）是一种显性性状。 所以它是纯合显性或杂合的（纯合显性= BB，杂合子= Bb），蓝色眼睛（b）是隐性性状（纯合隐性= bb）。 What is homozygous and …

On the other hand, if the alleles are different (can be distinguished) from each other, the genotype is heterozygous. In cases where there is only one copy of a gene present, for example if there is a deletion of the locus on the homologous chromosome, we use the term hemizygous.
