Answer:
-1.1
Explanation:
Data provided in the question:
Average temperature is rising at a rate, = 0.15°C/year
Rate of change rainfall, = - 0.1 cm/year
= -2
= 8
Now,
we need to calculate
since,
The wheat production (W) is dependent on the rainfall (R) and the Temperature (T)
thus, Using the chain rule , we have
=
+
on substituting the respective values, we get
= -2 × 0.15 + 8 × (-0.1)
or
= -0.3 - 0.8
or
= -1.1
To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.
If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.
p +q=1
0,3 +q=1
q= 1-0,3
q= 0,7
Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.
0,09 + 2pq +0.49= 1
2pq +0,58= 1
2pq= 1-0.58
2pq=0,42
The freqency of the heterozygotes in this population is 0.42
