MediumGive a scientific reason: Variations are expected in sexually reproducing plants.
(N/A) Sexual reproduction involves the formation of gametes in the gonads,meiosis,and the fusion of gametes.
These processes produce variations due to new combinations of genes resulting from crossing over,the random segregation of chromosomes,and the random fusion of gametes.
Consequently,daughter offspring are genetically different from their parents.
Thus,sexual reproduction serves as a primary source of variation within a population.
