It proves that living organisms MUST come from other living organisms, an egg couldn't magically appear in a pile of chicken seed, a hen would have had to lay the egg first, just as a nucleoulus makes ribosomes so the cell can have proteins, the proteins don't just materialize within the organism.

Answer:
Explanation:
From the question, the total population = 171 i.e (80+71+21)
Genetic frequency therefore; BB = 71/171 = 0.42
Bb = 80/171 = 0.47
bb = 20/171 = 0.12
Allele frequency therefore;
Allele B = 0.42+(0.50×0.47) = 0.66
Allele b = (0.50×0.47)+0.12 = 0.36
Note all values were rounded up to two significant figures
