The two most accepted hypotheses for hybrid vigor are dominance and overdominance. Dominance refers to the expression of one allele over another, while overdominance refers to the superiority of the heterozygote compared to either of the homozygotes. This can result in increased growth, fertility, and resistance to disease in the hybrid offspring.
