The correct answer is option:
The peak of the bell curve has shifted to the right, with a greater frequency of crickets with long legs and a lower frequency of crickets with short legs.
The given condition would lead the directional selection of the crickets with long legs. Directional selection leads to shifting of curve in one direction, which is more suitable.
The crickets with short leg get easily caught by predators, so, after sometime, there would be a decrease in number of the crickets with short leg. At the same time, the crickets with long leg would manage to save themselves and their number would comparatively increased.

drift is a predictable event alongside with natural selection, mutation, and
migration. In every era of generation, organisms’ genes may be passed on to its
species, to further the usable genetic trait while the not-so-used genes are
trashed away.</span>
Answer:
The correct answer will be- Non-Mendelian inheritance (incomplete dominance)
Explanation:
Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.
In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.
Cross
RR (red) x rr (white) = Rr (pink)
Thus, incomplete dominance is the correct answer.
Answer:
A gamma-ray, or gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist, and physicist discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation alpha rays and beta rays in ascending order of penetrating power.
