The latter group of mice is particularly interesting due to hybrid dysgenesis
resulting in undersize placentas and embryos.
2]s (or BCs) causes the breakup of the coadapted resistance mechanisms resulting in hybrid dysgenesis
A main emphasis has been on determining what genetic features contribute to postmating reproductive isolation, and how they evolve and interact to generate hybrid dysgenesis (Hewitt 1988).
11]) suggest that the centromeric segments of these chromosomes from the two subspecies are not compatible, thus leading to hybrid dysgenesis.
Even though the European house mouse hybrid zone has been the focus of numerous studies during the last two decades, the contrasting results obtained by different approaches demonstrate that the degree of hybrid dysgenesis
is not yet well defined.
