Phenotype dis-assortative mating

Phenotype dis-assortative mating

  • Mating between phenotypically dissimilar individuals belonging to the same population.
    Consequences:
    1. It leads to the maintainance or some increase in heterozygosity
    2. Reduction in population variance as to produces intermediate phenotype
    3. Due to increase in heterozygosity the correlation betweenrelatives or prepotency is reduced.
    4. This mating system is very useful in making a population stable i.e. in maintaining variability suitable parents may be selected to remove their weaknesses. The progenyfrom such a mating would be more desirable than the parent. It is useful in maintaining variability in small population as it reduces inbreeding.
