Population I. INTRODUCTION A population is all the organisms of the same group or species who live in the same geographical area and are capable of interbreeding. In ecology the population of a certain species in a certain area is estimated using the Lincoln Index.

Normally breeding is substantially

alleles in the gene pool of a population. Hardy and Weinberg‚ and the population geneticists who followed observed that evolution will not occur in a population if seven conditions are met: 1. Mutation is not occurring 2. Natural selection is not occurring 3. The population is infinitely large 4. All members of the population breed 5. All mating is totally random 6. Everyone produces the same number of offspring 7. There is no migration in or out of the population With their observations
