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

Harlamova29_29 [7]

Answer:

T T A G C C G T A A T G is the complementary DNA strand.

Explanation:

A=T G=C C=G T=A

this is the key to all DNA complementary strands.

(not sure what the "O" was at the end but- it's ok)

Hope this helps! :)

Suggest one reason why the population of the woodland caribou has declined in the united states?

schepotkina [342]

Well its most likely over hunted but if its endangered and not allowed to be hunted then it would be because of natural predators in the area being over populated and taking out the caribou to fast
