A scientist samples a population of butterflies and finds that 56% are heterozygous at a particular locus. If the population is
d1i1m1o1n [39]

0.44  the frequency of the homozygous individuals in this population.

What is Hardy-Weinberg principle ?

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

From the Hardy Weinberg Law of Population and Genetics,

We have

x²+2xy+y²=1 and

x+y=1

where

x = frequency of the dominant allele in the population

y = frequency of the recessive allele in the population

x2 = percentage of homozygous dominant individuals

y2 = percentage of homozygous recessive individuals

2xy = percentage of heterozygous individuals

Given 2xy = 0.56

from here, y=0.28/x, (the frequency of the recessive allele ) can be obtained

we need to find 'x'

recall, x+y=1, x=1-y

substituting this gives us

y=0.28/(1-y), which becomes,

y(1-y)=0.28

y²- y + 0.28 (quadratic equation)

Solving this to find 'y' gives two imaginary values of y = 0.44 but ,

There is no imaginary solution  .

Crank

A biological theory, like the theory of evolution, that is widely accepted and supported by so many observations and experiments may be referred to as a principle or a law.

<h3>What is a Law?</h3>

This refers to statements which describes or predict a range of natural phenomena as a result of repeated experiments which has been performed and the authenticity has been prove by peers and other individuals.

A law is also referred to as principle and has been observed to be always true unlike due to the repeated scientific methods being done approving of its validity thereby making law the correct choice.
