3. One example is burrowing behaviour in oldfield mice, on which a genetic study was performed very recently (Weber, Peterson & Hoekstra, Nature 2013); there are discrete genetic modules that change behaviour, resulting in a significant difference in burrow shape and construction. Extended Phenotype was a concept first introduced by author Richard Dawkins in his book the Extended Phenotype. The viral gene that manipulates climbing behavior of the host was identified, providing evidence of a genetic basis for the extended phenotype.

The concept of phenotype can be extended to variations below the level of the gene that affect an organism's fitness. The third and final extended phenotype is action at a distance. An example is the manipulation of host behavior by cuckoo chicks. 0. ... which of the following might be considered an "extended phenotype"?

A recurring example of this type of extended phenotype is the manipulation of the host’s behavior by cuckoo chicks (group of birds of the Cuculidae family). 3. Although the “extended reach” of the gene is introduced in “The Selfish Gene,” the focus is on the gene itself. 0. Learn vocabulary, terms, and more with flashcards, games, and other study tools. An example of the latter scenario: A patient has what appears to be an anti-Fy a, anti-e, and possibly anti-K, with no evidence of an autoantibody. “The Extended Phenotype” is a more difficult read for the non-scientist that “The Selfish Gene” but it is “manageable” with some re-reading of key passages. The basic premise of this concept is that the term 'phenotype' should not be limited to view the full answer ... the example of potato washing by Imo and other Japanese macaques showed that behavioral innovations generally. This patient is phenotyped for those three antigens, and is found to be Fy a -negative and e-negative, but is K-positive. These are part of the physical " readout " of the genes, the extended phenotype of the replicating code. Start studying Anthropology: Final Exam Review. phenotype Sentence Examples. However, mis-sense mutation associated with a mild phenotype might be missed in aggregation studies depending on the dose of agonist used. An extended phenotype is the behavioural phenotype of a gene (optimon). In this case the chick is not physically associated with the host, as in the case of hairworms, but nonetheless influences the expression of its behavioral phenotype.
Gypsy moths infected by a baculovirus climb to the top of trees to die, liquefy, and “rain” virus on the foliage below to infect new hosts. For example, silent mutations that do not change the corresponding amino acid sequence of a gene may change the frequency of guanine - cytosine base pairs ( GC content ).
