20 Μαρ 2024 · If you are homozygous for a particular gene, it means you inherited the same version of that gene from both your mother and father. If you are heterozygous for a particular gene, it means you inherited two different versions of the gene, one from your mother and one from your father.
There are two types of genetic heterogeneity: allelic heterogeneity, which occurs when a similar phenotype is produced by different alleles within the same gene; and locus heterogeneity, which occurs when a similar phenotype is produced by mutations at different loci.
17 Αυγ 2021 · An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait.
3 Αυγ 2023 · Homozygous is a genetic condition where an individual inherits the same alleles of a gene from both the parents. Heterozygous is a genetic condition where an individual inherits different alleles of a gene from the two parents. Genotype representation
When both loci of a gene, on homologous chromosomes, possess distinct and different alleles, the organism is said to be heterozygous for that particular gene, and can also be referred to as a heterozygote.
Heterogeneity is observed at the genetic and phenotypic level, where genetic heterogeneity captures the diversity of genetic alterations in tumor cells (e.g., point mutations, indels, structural variants), and phenotypic heterogeneity refers to how cells from the same genetic background can present different phenotypic states (e.g., morphology ...
