Inbreeding results in homozygosity which can increase the chances of offspring being affected by recessive traits. [3] In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population [ 4 ] [ 5 ] (called inbreeding depression ), which is its ability to survive and reproduce.
Inbreeding can be referred to as homogamy. [1] ... Assortative mating is the choosing of a mate to breed with based on their physical characteristics, ...
Though there are many traits about zebrafish that are worthwhile to study including their regeneration, there are relatively few inbred strains of zebrafish possibly because they experience greater effects from inbreeding depression than mice or Medaka fish, but it is unclear if the effects of inbreeding can be overcome so an isogenic strain ...
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Opposite to the practice of mating animals of different breeds, purebred breeding aims to establish and maintain stable traits, that animals will pass to the next generation. By "breeding the best to the best", employing a certain degree of inbreeding , considerable culling , and selection for "superior" qualities, one could develop a bloodline ...
The resulting offspring displays physical characteristics of either parent, or a mix of characteristics from both, periodically producing a fleeced llama. The results are increasingly unpredictable when both parents are crossbreeds, with possibility of the offspring displaying characteristics of a grandparent, not obvious in either parent.
The ultimate traits most salient to female human mate choice, however, are parental investment, resource provision and the provision of good genes to offspring. Many phenotypic traits are thought to be selected for as they act as an indication of one of these three major traits.
In evolutionary psychology and behavioral ecology, human mating strategies are a set of behaviors used by individuals to select, attract, and retain mates.Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring.
