Summary Introduction

To predict: How genetic drift and natural selection could affect a population, where a sudden change in the condition of the environment, has caused a drop in the carrying capacity of the population.

Concept introduction: K or the Carrying capacity is defined as the environment that can sustain maximum size of the population. The distribution of organisms on land is influenced greatly by the climatic conditions. Climatic condition is defined as the long term weather condition that prevails in an area for a longer period. Carrying capacity of a population can be affected because of the natural selection and genetic drift.
