The American pika (Ochotona princeps) is known to maintain strict territorial boundaries, and dominance between individuals is enforced through a dominant pika invading another pika's territory, forcing the latter out. The general hierarchy of dominance has been observed (higher to lower in dominance) from male to female and adult to juvenile.
For many animal societies, an individual's position in the dominance hierarchy corresponds with their opportunities to reproduce. [6] In hierarchically social animals, dominant individuals may exert control over others. For example, in a herd of feral goats it is a large male that is dominant and maintains discipline and coherence of the flock.
Biochemistry, Molecular biology, Genetics: Animal Model: Used for researching diseases and disorders in humans. Some animals may have human-like traits, such as mice, while others may have traits that are ideal for research, such as the squid giant axon: Biochemistry, Neuroscience, Physiology: Biological ablation
Co-dominance in a Camellia cultivar A and B blood types in humans show co-dominance, but the O type is recessive to A and B. This Punnett square shows co-dominance. In this example a white bull (WW) mates with a red cow (RR), and their offspring exhibit co-dominance expressing both white and red hairs.
An example in dog coat genetics is the homozygosity with the allele "e e" on the Extension-locus making it impossible to produce any other pigment than pheomelanin. Although the allele "e" is a recessive allele on the extension-locus itself, the presence of two copies leverages the dominance of other coat colour genes.
A harem is an animal group consisting of one or two males, a number of females, and their offspring. The dominant male drives off other males and maintains the unity of the group. If present, the second male is subservient to the dominant male. As juvenile males grow, they leave the group and roam as solitary individuals or join bachelor herds ...
The management of issues regarding animal genetic resources on the global level is addressed by the Commission on Genetic Resources for Food and Agriculture (CGRFA), which is a body of FAO. In May 1997, The CGRFA established an Intergovernmental Technical Working Group on Animal Genetic Resources for Food and Agriculture (ITWG-AnGR). [31]
Many examples of genetic factors of social behavior have been derived from a bottom-up method of altering a gene and observing the change it produces in an organism. Sociogenomics is an integrated field that accounts for the complete cellular genetic complement of an organism from a top-down approach, accounting for all biotic influences that ...
