A fruit fly population has a gene with two alleles, A1 and A2. Tests show that 70% of the gametes produced in the population con
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

3. Which of the following would not prevent an mRNA from being transported to the rough endoplasmic
Delicious77 [7]

Answer:

3 The mRNA was not bound to by a ribosome  4 tRNA: anticodon matching  5 switching from normal nucleotide for an abnormal one .

Explanation:

3  If the mRNA is not bound to the ribosome then this do not prevent the mRNA from being transported to the Endplasmic reticulum in the cytoplasm.This because binding of ribosome to the mRNA is essential after the mRNA has reached the cytoplasm to initiate the process of protein synthesis.

4 tRNA contains Anticodons that interact with the codon present in the mRNA to bring an amino acid specific for that codon to the A site of ribosome.

5 Mutation at the 3" nucleotide reading frame switch a normal nucleotide for an abnormal one.
