Webb24 dec. 2024 · In genetics, the term “homolog” is used both to refer to a homologous protein and to the gene ( DNA sequence) encoding it. As with anatomical structures, homology between protein or DNA sequences is defined in terms of shared ancestry. Webb16 juni 2024 · This type of inheritance pattern is known as the polygenic inheritance pattern. Biology definition: Polygenic inheritance is a non-Mendelian pattern of inheritance in which a particular trait is produced by the interaction of genes at many loci (i.e. polygenes). Etymology: “poly”, meaning “many”. Compare: monogenic inheritance.
WebbThis definition includes genes that do not encode proteins (not all transcripts are messenger RNA). The definition normally excludes regions of the genome that control transcription but are not themselves transcribed.
