POSSIBLE P Why is an energy pyramid smaller at the top than at the base?
the animals at the top are not good at hunting so there are less of them
The amount of energy available to top predators is greater than the amount of energy available to produce
The energy available to top predators decreases as you move up the pyramid so it limits the size of the
predator population
O the mass of all the predators at the top is greater than all the plants at the bottom

we solve the problem using the hardy-wineberg equation.

let us start with the homozygous recessive proportion of individuals with sickle cell anaemia,

we have the proportion as q² = 0.25.

∴ q = 0.5 (frequency of hbs in population)

further,

solving for the frequency of normal cell by using the fact that,

p + q = 1

∴ p = 1 - 0.5 = 1 - 0.5 = 0.5

now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous carriers of sickle cell anaemia,

∴ 2pq = 2 x 0.5 x 0.5 = 0.5

and the homozygous normal cell individuals proportion is given by the expression,

∴ p² = 0.5² = 0.25

hence, the carriers for sickle cell anaemia are in proportion, 0.5, or 50%.
