Answer:
Yes, the population is evolving
Explanation:
Hardy-Weinberg equilibrium states that a population is not evolving if it is in hardy weinberg equilibrium as the alleles frequency do not change over time in generations.
In mathematical equation, the genotype frequency will be -P²+2Pq+q²=1 and allele frequency will be p+q=1, where p = dominant allele and q will be recessive allele.
In the question, since the observed genotype are-
P² - VV= 16
2Pq- Vv- 92
q²- vv- 12
<u>1. Calculate allele frequency</u>
Now we will calculate if the expected value is same or close or not.
We will calculate allele frequency
Population has 120 individuals which means it has - 240 alleles.
In which V (p) will be- 32 +92= 124 allele
p- dominant allele/ total allele= 124/ 240 = 0.52
P= 0.52
q will be 1-0.52= 0.48
<u>2. Expected genotype frequency</u>
Now we will calculate expected genotypic frequency.
P²- 0.52 X 0.52= 0.27
2Pq = 2 x 0.52x 0.48 = 0.5
q²= 0.48 x 0.48 = 0.23
<u>3. Expected progeny </u>
P²= 0.27 x 120= 32 VV
2Pq= 0.5 X 120= 60 Vv
q²= 0.23 x 120= 28 vv
Since the observed value is not equal to the expected value therefore the population is not in Hardy- Weinberg equilibrium and the population is evolving.
Thus, Yes, the population is evolving is correct.
