Name the phenomenon that governs the following: -5i) 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

Answer 1

i) Green beetles living in green bushes are not eaten by the crows. - Camouflage

ii) Number of blue beetles in green bushes increases, only because the red beetles living there were trampled by a herd of elephants.- Natural Selection

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

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

Answer 2

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