Dennis_Churaev [7]

Answer:

Explanation:

Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.

From the data set given, the total number of the population is:

43+9+32+110 = 194

However, their ratio are being calculated as follows:

43/194 = 0.22

9/194 = 0.05

32/194 = 0.16

110/194 = 0.57

After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.

i.e.  

3/16 = 0.18

1/16 = 0.06

3/16 = 0.18

9/16 = 0.56

The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.

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%
