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%

3. Which is not an example of symbiosis?
S_A_V [24]

Answer:

The correct answer is B. generalism.

Explanation:

Mutualism is a symbiotic relationship wherein both organisms benefit from the other’s presence. Parasitism is a symbiotic relationship wherein one organism benefits at the expense of the other organism, which is harmed. Finally, commensalism is a symbiotic relationship wherein one organism benefits and the other is neither helped nor harmed. Generalism does not refer to a symbiotic relationship and thus is the correct response.

Hope this helps!
