Why is vivipary an undesirable character for annual crop plants ?

• It reduces the vigour of plant

• The seeds cannot be stored under normal conditions for the next season

• The seeds exhibit long dormancy

• It adversely affects the fertility of the plant

Assertion: Inbreeding increases homozygosity, thus exposes harmful recessive genes, which are eliminated by selection.

Reason: Continued inbreeding reduces fertility and productivity.
