Triacylglycerols or triglycerides are lipids that store energy and are typically composed of multiple building blocks containing three fatty acids attached to a glycerol molecule.
Explanation:
Triglycerides belong to the group acylglycerols of lipids which are characterized by the combination of glycerol and fatty acid molecules.
64% of the population have dominant phenotype which means they’re either BB or Bb. The other 36% of the population have bb genotype. If this population is in equilibrium then f(b)=rad0.36=0.6 and as u know f(b)+f(B)=1. So 1-0.6=0.4.
