A study on the association of alpha males and females during the non-breeding season in wild Capuchin monkeys examined whether alpha males are the preferred mate for females and, secondly, whether female-alpha status and relationship to the alpha-male can be explained through the individual characteristics and or social network of the female. [4]
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.
Visual communication is a common dominance signal among animals. They are an effective modality as they come at a low cost to the animal and minimize risk. The Gila Monster (Heloderma suspectum) for example, express bright orange splotches during territorial conflict to warn competitors that they are poisonous, and thus assert their dominance over a territory.
Example of a pedigree chart using Ahnentafel numbering. A pedigree chart is a diagram that shows the occurrence of certain traits through different generations of a family, [1] [2] most commonly for humans, show dogs, and race horses. [citation needed]
An example of a botanical genetic polymorphism is heterostyly, in which flowers occur in different forms with different arrangements of the pistils and the stamens. The system is called heteromorphic self-incompatibility , and the general 'strategy' of stamens separated from pistils is known as herkogamy .
Since dominant traits mask recessive traits (assuming no epistasis), there are nine combinations that have the phenotype round yellow, three that are round green, three that are wrinkled yellow, and one that is wrinkled green. The ratio 9:3:3:1 is the expected outcome when crossing two double-heterozygous parents with unlinked genes.
Typically, only the dominant pair in a group breeds, and a litter of young is reared annually in an underground den. Canids communicate by scent signals and vocalizations. [3] One canid, the domestic dog, entered into a partnership with humans at least 14,000 years ago and today remains one of the most widely kept domestic animals. [4]
The colour of the rabbits is governed by two incompletely dominant traits: black fur, represented by "B", and white fur, represented by "b". A rabbit in this population with a genotype of "BB" would have a phenotype of black fur, a genotype of "Bb" would have grey fur (a display of both black and white), and a genotype of "bb" would have white fur.
