Top: An ancestral gene duplication produces two paralogs (histone H1.1 and 1.2). A speciation event produces orthologs in the two daughter species (human and chimpanzee). Bottom: in a separate species , a gene has a similar function (histone-like nucleoid-structuring protein) but has a separate evolutionary origin and so is an analog.
English: Top: An ancestral gene duplicates to produce two paralogs (Genes A and B). A speciation event produces orthologs in the two daughter species. Bottom: in a separate species, an unrelated gene has a similar function (Gene C) but has a separate evolutionary origin and so is an analog.
Syntelog: a special case of gene homology where sets of genes are derived from the same ancestral genomic region. This may arise from speciation events, or through whole or partial genome duplication events (e.g. polyploidy).
Desert hedgehog, also Desert hedgehog homolog or Dhh, is a protein encoded by the DHH gene, and is a member of the hedgehog signaling pathway. The human homolog (DHH) is on chromosome band 12q13.1. [ 5 ] [ 6 ] The protein encoded by this gene is involved in cell signaling .
Music therapy is a systematic process; it is not a series of random events. Systematic means that music therapy is "purposeful, organized, methodical, knowledge-based, and regulated" (Bruscia 1998). One of the most important features is its methodical processes. Methodical means that music therapy always proceeds in an orderly fashion.
The concept of musical gestures encompasses a large territory stretching from details of sound-production to more global emotive and aesthetic images of music, and also include considerations of cultural-stylistic vs. more universal modes of expression. In all cases, it is believed that musical gestures manifest the primordial role of human ...
Biomusicology is the study of music from a biological point of view. The term was coined by Nils L. Wallin in 1991 to encompass several branches of music psychology and musicology, including evolutionary musicology, neuromusicology, and comparative musicology.
Inparanoid is an algorithm that finds orthologous genes and paralogous genes that arose—most likely by duplication—after some speciation event. Such protein-coding genes are called in-paralogs, as opposed to out-paralogs (which arose prior to a species split).
