Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).
Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).

Hope this helps xox :)
The motor unit is composed of both the skeletal and muscular systems.
The change in adolescence all begins as a child in their unique combination of genes<span>, brain development, environment, experiences with family and friends, and community and culture. Social and emotional changes show that they are growing independently and learning how to be an adult. Physical change in different genders are really different because both are going into puberty and so they begin to see alot of differences in their bodies. Adolescence mental starts on what they begin to see and believe, and as everything is developing in their mind many of those things stay, what they have in mind depends on them. Adolescence are still maturing to become adults.
