Personality traits are patterns of thoughts, feelings and behaviors that reflect the tendency to respond in certain ways under certain circumstances. [ 1] Personality is influenced by genetic and environmental factors and associated with mental health. [ 2] Beside the environment factor, genetic variants can be detected for personality traits.
These gene variations were unlikely to have been the result of natural evolution, and indicate selection on both morphology and behavior during dog domestication. These genes have been shown to affect the catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight response [63] [64] (i.e. selection for tameness ...
Dog coat color is governed by how genes are passed from dogs to their puppies and how those genes are expressed in each dog. Dogs have about 19,000 genes in their genome [2] but only a handful affect the physical variations in their coats. Most genes come in pairs, one being from the dog's mother and one being from its father.
According to Candille, et al. (2007), dog coat color can largely be explained by three genes: MC1R, Agouti and CBD103. When a dog has wild-type alleles at all three genes, it will have a yellow coat. When the dog has a loss-of-function allele at MC1R, it will have a yellow coat regardless of the genes it carries on the other two genes. Only a ...
linkage disequilibrium (two neighboring genes tend to be inherited together, each affecting a different trait) biological pleiotropy (a single gene having multiple otherwise unrelated biological effects, or shared regulation of multiple genes [39]) mediated pleiotropy (a gene affects trait X and trait X affects trait Y).
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. It seeks to explain how nurture shapes nature, where nature refers to biological heredity and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins).
The study of animal personality is largely based on the observation and investigation of behavioural traits. In an ecological context, traits or ‘characters’ are attributes of an organism that are shared by members of a species. Traits can be shared by all or only a portion of individuals in a population.
The genetics of social behavior is an area of research that attempts to address the question of the role that genes play in modulating the neural circuits in the brain which influence social behavior. Model genetic species, such as D.melanogaster (common fruit fly) and Apis mellifera (honey bee), have been rigorously studied and proven to be ...
