In a population of plants, the allele for long stems is completely dominant over the allele for short stems. If 35% of the popul
KatRina [158]
Assumptions:
1. Equilibrium has been reached for the allele proportions
2. Absence of <span>evolutionary influences such as </span>mate choice<span>, </span>mutation<span>, </span>selection<span>, </span>genetic drift<span>, </span>gene flow<span> and </span>meiotic drive<span>.
</span>
Defining L=long stem, l=short stem, and L is dominant over l.
f(x) = frequency of allele x  (expressed as a fraction of population)
Then the Hardy-Weinberg equilibrium law applies:
p^2+2pq+q^2=1
where 
f(LL)=p^2
f(Ll)=2pq
f(ll)=q^2

Given f(ll)=0.35=q^2, we have
q=sqrt(0.35)=0.591608
p=1-q=0.408392
=>
f(Ll)
=2pq
=2*0.408392*0.591608=0.483216
= proportion of heterozygous population

Answer: percentage of heterozygous population is 48.32%

If a physical change has taken place, which of these is most likely true?
Katena32 [7]

A physical change means that none of the atoms or chemical bonds have been changed inside of something. Therefore, if you make a physical change, you should be able to revert it back. That means that the answer to this question is "The changed substance retains its unique properties." because it is the only answer choice where nothing major is being changed. The rest of the answer choices indicate that once changed, it isn't able to be changed back.

The graph indicates that the mean of the treatment is Smaller than the mean of the placebo

The graph shows that the treatment's mean is lower than the placebo's mean.

The following graphs display several data sets that illustrate how medication affects how quickly you recover. Each graph with a statistically significant distinction between the placebo and the experiment should be clicked.
