Question

Name the phenomenon that governs the following: -
i) Green beetles living in green bushes are not eaten by the crows.

ii) Number of blue beetles in green bushes increases, only because the red beetles living there were trampled by a

herd of elephants.

iii) No ‘medium height plants’ are obtained in F1 generation, upon crossing pure tall and dwarf pea plants.

iv) Tails of mice were surgically removed for several generations; still mice had tails in the following generations.

v) A migrant beetle reproduces with the local population; as a result genes of migrant beetle enter the new

population.

Answer 1

Natural selection is the phenomenon that governs the green beetles living in the green bushes are not eaten by the crows.

According to Darwin theory, the natural selection, along with genetic drift, mutation and migration is a key of evolution. In the way we can find both brown and green beetles in the green bushes but the we can find more number of green beetles than brown one.  

Green Beetles are evolved to not to be spotted by any birds in a green environment where brown beetles can be easily spotted and eaten.
