Question : Hardy-weinberg equilibrium. |
| Answer» Solution :(1)Hardy and weinberg were TWO SCIENTIST who proposed a concept of genetic equilibrium popularly known as hardy-Weinberg PRINCIPLE or equilibrium.(2)this principle states that gene,allel,or genotype frequencies remain the same from GENERATION to generation unless disturbed by factors like mutation,nonrandom mating,genetic drift,etc.(3)For EXPLAINING the concept of equilibrium they assumed that there are two alleles located at a single locus (A and a).(5)The frequency of genotype AA is `P^(2)`,for 2Aa is 2pq for aa is `q^(2)`(6)The equilibrium equation is `p^(2)+2pq+q^(2)=1`.(7)It says that if sum total of gene frequenceies is 1 then sum total of genotype frequenceis is also equal to 1.When the equilibirium is disturbed then only evolution occurs. | |
