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

b)

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 of the following is an indicator that a finding may be "junk" science?
liubo4ka [24]

Answer: a.The study is funded by a group with a financial interest in the outcome.

Explanation:

Junk science is a term that is used to describe scientific research or data that is false and fraudulent and is usually presented in order for the people behind it to be able to push an agenda or assertion.  

If a study is funded by a group with a financial interest in the outcome, the research could end up being junk science as the backs might persuade the researchers to manipulate the data in such a way that it would favor them.

For instance, a Big Tobacco funded research into lung cancer finding that smoking does not contribute as much as previously thought to lung cancer
