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%

Strike441 [17]

Answer:

c. Fungi

d. Yeast

Explanation:

Both fungi and yeast will be effectively removed by a 0.22 micron pore size filter.

<em>The size of microscopic fungi ranges from 2 to 10 microns  while the size of yeast ranges from 3 to 4 microns in diameter. Hence, both organisms will be effectively filtered off by a 0.22 micron filter paper.</em>

The size of bacteria ranges from 0.2 to 2 microns while that of virus is in nanometer. Hence both cannot be effectively removed by a 0.22 micron pore size filter paper.

The correct options are c and d.
