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.
English: Example of the pedigree of a hereditary, genetic trait being transmitted through (3) generations, doing so in an autosomal dominant fashion Pedigree itself: -A man with a genetic variant (red hexagon) has children with a woman without the genetic variant (white circle)
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 ]
A hereditary carrier (genetic carrier or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease. Carriers are, however, able to pass the allele onto their offspring, who may then express the genetic trait.
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).
