Hello Aspirant

In a population of plants ,some were extremely tall and the remaining were extremely dwarf .none of the plants of the populations showed an intermediate height .the type of operation of natural selection is STABILIZING.

DEFINATION

When selective pressures select against the two extremes of a trait, the population experiences stabilizing selection. For example, plant height might be acted on by stabilizing selection. A plant that is too short may not be able to compete with other plants for sunlight. However, extremely tall plants may be more susceptible to wind damage. Combined, these two selection pressures select to maintain plants of medium height. The number of plants of medium height will increase while the numbers of short and tall plants will decrease.

Hope it helps

Thank you & Good Luck!!!
