Outbreeding is a cross between genetically unrelated individualities.
The genetically variant individuals are those who have no similar genotype in a minimum of six generations.
Outbreeding is a controversial cross system.
It raises heterozygote situations in the population, that contains the combined alleles of parents.
All genes are combined more frequently, so it increases combinative diversity.
Although the diversity is increased, the original homozygous parental traits are often suppressed over multiple rounds of outbreeding leading to an increased expression of the intermediate genotype rather than the original parental genotype.
Outbreeding depression occurs when the central traits make an organism less fit compared to either of its maternal or paternal forms.
