In a certain population, the frequencies of two alleles A and a are equal. The population inbreeds such that f = 0.3. What is the frequency of each genotype in the population? Multiple Choice AA: 0.35, Aa: 0.3, aa: 0.35 AA: 0.325, Aa: 0.35, aa: 0.325 AA: 0.25, Aa: 0.5, aa: 0.25 The genotype frequencies cannot be calculated from the provided information.



Answer :

The frequency of AA individuals is 0.25, the frequency of Aa individuals is 0.5, 0.25 the frequency of aa individuals is

What is frequency?
The frequency of a repeating event is its number of instances per unit of time. In some cases, it is also referred to it as temporal frequency or ordinary frequency to emphasise differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is expressed. The period is indeed the reciprocal of a frequency because it is the length of time for one cycle in a repeating event. When a heart beats 120 times per minute (2 hertz), for instance, the period (T), or space between beats, is half a second. In science and engineering, frequency is a crucial parameter for describing the temporal rate of change seen in oscillatory as well as periodic phenomena.

Let q and p represent the frequency of each allele, respectively.
If A and a have equal frequencies, then p = q = 0.5
because p + q = 1. The equation p2+2pq+q2 = 1
can be used because the population has been in
Hardy-Weinberg equilibrium.

As a result, the frequency of AA individuals is p2 = 0.52 = 0.25,
the frequency of Aa individuals is 2pq = 2 x 0.5 x 0.5 = 0.5,
and the frequency of aa individuals is q2 = 0.52 = 0.25.
