In humans, albinism (unpigmented skin, hair, and eyes) is due to an enzymatic deficiency, and it is an autosomal recessive trait. Suppose that in a small country of one million people (“Generation 1”), there are 500 aa albinos and 9000 Aa heterozygous carries. If the Generation 1 follow the Hardy-Weinberg equilibrium?

a) then the number of homozygous aa albino individuals would be equal to P2

b) there were 500 albino individuals in generation one.

c) then the number of homozygous aa albino individuals would be equal to q2

d) there were 25 albino individuals in generation one.

Which of the following is the correct prediction about the hardy-weingburg equilibrium?

Precision will be reduced, but yield will be increased

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.
