(a) (p+q)2=p2+2pq+q2=1,represents an equation used in population genetics lt is a mathematical representation of 'Hardy Weingborg principlc'. Thhis principle says that allele frequncies in a population are stable and is constant from generation to generation, i.e., the gene pool remains a constant.
