Answer:

The scientist's conclusion is most likely unreliable because he just interviewed people watching movies in the theatre. He should have interviewed an equal number of people from the theatre and from home to get reliable results. According to the scientific method for designing an experiment, the experiment or survey conducted by scientists is not correct. Hence, the scientist's conclusion is wrong because his method of experimentation was wrong.

IceJOKER [234]

Answer:

Option C

Explanation:

Given ,

A1 allele is carried by 70 % people

Let us assume A1 s dominant genotype

This means p= \frac{70}{100} = 0.7

Thus, frequency of allele in the given population is 0.7

It is also given that the population is in Hardy-Weinberg equilibrium thus

p+q=1\\0.7+q=1\\q = 1-0.7\\q= 0.3

Frequency of fruit fly with genotype A2A2 will be

q^2\\= (0.3)^2\\= 0.09

As per Hardy-Weinberg's second equation of equilibrium

p^{2} + q^{2} + 2pq = 1\\0.49+0.09+2pq = 1\\2pq = 1-0.49-0.09\\2pq= 0.42

Hence, option C is correct
