Solution

The correct option is C Yields progeny which are not genetically variable
self-pollination causes an increase in homozygosity in progeny in every generation of selfing up to approximately 96% in the F5, and selfing of homozygous line produce genetically similar progeny with negligible or little variability. So, the correct option is C. ( Yields progeny which are not genetically variable )
