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

written description of how carbon moves through the biosphere, atmosphere, hydrosphere, and geosphere.
Anna35 [415]
<span>Carbon is present in the biosphere and other systems of the planet and is an essential part of life. Carbon moves through these systems by feeding the heterotrophs of other organisms, through the consumption of dead organisms. When oxygen is present, there is aerobic respiration, which releases carbon dioxide into the surrounding air or water. It plays an important role in the structure, biochemistry, and nutrition of all living cells.</span>
