Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a <span>generator to create electricity.</span>

Answer:

Windmills (wind turbines) are generally made up of 2-3 blades that are also considered as the propeller-like blades and this is fixed about the rotor at the top of a pillar or tower at a height of about 80-100 feet. This is because the wind is generally fast at about this height.

The rotor is again fixed to a major shaft, and when the prevailing wind is high enough in that area then the turbines rotate and due to this rotation, the generator within the major shaft starts spinning thereby produces the electricity. Thus they are one of the efficient ways of using wind energy.

A pea plant with genotype PP (purple flowers) mates with a plant with the genotype pp (white flowers). The dominant allele P cod

Basile [38]

In the question, it is given that the purple flowers are dominant to the white flowers. The dominant allele for the flower is P, and the recessive allele for the flower is p.

So, the possible genotypes of the purple flower is - PP or Pp.

And, the possible genotype of the white flower is - pp.

The cross1 shows the cross between PP and pp.

The phenotype of all the offspring in the cross 1 is Purple, and the genotype is pp. Hence, the possibility of getting purple flowers in the progeny is 100%.

Homozygous dominant genotype is the condition, in which the plant's alleles are same and both are dominant.

The cross 2 shows the cross between Pp and pp:

The homozygous dominant genotype (PP) is 1 and the total number of progeny is 4. So, the probability of occurence of PP is 1/4 or 25%.

Hence, the first blank can be filled with 100% and the second blank can be filled with 25%.
