Wind energy is a reusable resource of energy thus, is environmentally useful. As reusable, it doesn't give off any type of gas/heat energy harmful to the environment/ the ozone layer, it is considered an eco-friendly source of energy. But, as wind energy requires turbines, and turbines require wind, the wind and air pressure of the area matters as more the wind, more effective the wind energy. Wind energy and other reusable sources are often referred as economically expensive as installing the turbines over large plots of land is expensive and also reduces the area for home building etc, leaving more homeless people.

A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotyp
lana [24]

Answer:

Frequency of allele A1- 0.41

Explanation:

In Hardy weinberg equilibrium,

P refers to the dominant allele

q refers to the recessive allele

The allele frequency will be p+q=1

The genotypic frequency is- P²+q²+2pq=1

P²= genotype of dominant trait ( A1A1)- 77

2pq= genotype of heterozygotes (2pq)- 65

q²= genotype of recessive trait (A2A2)-  123

Total number of offsprings= 77+  65+ 123

                                            = 265

Now to calculate allele frequency of A1=

\dfrac{\text{number of A1A1 offspring}}{ \text{total number of offspring}}+\dfrac{1}{2}(\dfrac{\text{number of A1A2 offspring}}{\text{total number of offspring}})

= 77/265 + 1/2( 65//265)

=  0.290+ 0.122

= 0.413

Thus, 0.41 is correct.
