      Solution

      Self-pollination leads to a very rapid increase in homozygosity. Therefore,  populations  of  self-pollinated  species  are  highly  homozygous,  self-pollinated species do not show inbreeding depression, but may exhibit considerable heterosis. The aim of breeding methods generally is to develop homozygous varieties.
