Restriction enzyme cuts samples of DNA at restriction site; produces different lengths of DNA segments
A high level of gene flow into a population increases genetic diversity in a population. A high level of gene flow out of a population decreases genetic diversity in a population. Genetic drift is the change in allele frequencies due to "sampling error" factors. Typically, genetic drift has the biggest impact on small populations.
Gene flow (or gene migration) is a mechanism of evolution (change the allele frequencies) which transfers genetic variation among populations due to migration. High level of gene flow decreases the genetic differentiation between the two populations.
Genetic drift is a mechanism of evolution that acts by chance (“sampling error”) often when a population is reduced in size by a natural disaster (bottleneck effect) or when a small group leaves the main population and forms a colony (founder effect).
Answer:
Evolution of management is the concept that was developed in the early days of men when the realization was made that we must live in groups for the survival.
Explanation:
- Since men saw and realized that they need to live in groups, mighty men in the past were able to organize the masses, share them into various groups. The sharing was done accord to the masses' strength, mental capacities and intelligence.
- The evolution of management section is mainly divided into four sections:
- Early Management Thought
- The Scientific Management Era
- The Social Person Era
- The Modern Era
