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]
With dominant traits, one can still see the expression of the traits and can remove those traits, whether one outcrosses, line breeds or inbreeds. With recessive traits, outcrossing allows for the recessive traits to migrate across a population. Many traits are Mendelian and therefore exhibit a more complicated intermediate phenotype.
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.
Roan is a simple dominant trait symbolized by the Rn allele. [1] Traits that are dominantly inherited cannot skip generations, meaning that two nonroan parents cannot produce a roan offspring. [ 4 ] In cases where roan has appeared to skip generations, one of the parents is usually discovered to be slightly roaned. [ 6 ]
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]
A dominant gene that reduces the number of toes resulting in a "lobster-claw" appearance. This is considered an undesirable mutation. Polydactyly There are probably many genes, both dominant and recessive, that cause polydactyly in cats. Most cases of polydactyly in cats are perfectly harmless. Pd Thumb-cat polydactyly gene.
An early study suggested that the fold is inherited as an autosomal dominant trait. [8] A later study suggested an incomplete dominance. [9] A cat with folded ears may have either one (heterozygous) or two copies (homozygous) of the dominant fold gene (Fd). A cat with normal ears should have two copies of the normal gene (fd).
