Assume a population of purple and white flower pea plants (2000 total plants) is in Hardy-Weinberg equilibrium. The frequency of

lys-0071 [83]

Answer:

a) $0.48$

$p= 0.4\\q=0.6$

c) $720$

Explanation:

Given ,

Frequency of white flower plant ( $p^2$ ) is $0.16$

Thus, frequency of dominant white allele ( $p$ ) is equal to $\sqrt{0.16} \\= 0.4$

As we that, as per Hardy-Weinberg equilibrium equation

$p+q=1$

Substituting the value of $p$ in above equation, we get

$0.4+q=1\\q=1-0.4\\q=0.6$

a) As per Hardy-Weinberg equilibrium equation

$p^2+q^2+2pq=1\\$

Substituting the given and calculated values in above equation, we get -

$0.4^2+0.6^2+2pq=1\\0.16+0.36+2pq=1\\2pq=1-0.16-0.36\\2pq=0.48$

b) The frequency (decimal form) of the dominant allele

$p= 0.4\\q=0.6$

c) number of homozygous purple flower plants

$=$ frequency of purple flower plants ( $q^2$ ) $*$ Number of flowers

$= q^2 * 2000\\= (0.6^2)*2000\\= 0.36 * 2000\\= 720$

Which example below is a concern related to nuclear energy?

Kipish [7]

Answer:

C. can be unsightly and/or noisy

Explanation:

Answers A, B, and D correspond with fossil fuels (fracking, coal/gas mines), wind/environmentally-powered energy (turbines), and hydroelectric power (dams).

"Noisy" and "unsightly" are the most accurate descriptions of the nuclear energy process.
