C Homozygosity Correct Answer Incorrect Answer
D Heterosis Correct Answer Incorrect Answer

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.
