Abstract:Conditions for the maintenance of males in androdioecious populations (populations with both male and hermaphrodite individuals) have been derived for four different one-locus two-allele models of inheritance of androdioecy. The results are not in general accordance with those already known: depending on the mode of inheritance, males can be maintained irrespective of their fertilities. If males are sufficiently fertile, it may happen that they are maintained only for intermediate selfing rates of the hermaphrodites. A result already found for gynodioecy is confirmed for androdioecy, namely, that a 1ratio1 sex ratio is immediately established among zygotes if hermaphrodites appear as heterozygotes only.
Keywords:Selection  Biallelic  Inheritance  Androdioecy  Sex polymorphism
