population characteristics
(Science: epidemiology) Qualities and characterization of various types of populations within a social or geographic group, with emphasis on demography, health status, and socioeconomic factors.
This lesson looks at population attributes, regulation, and growth. It also covers population genetics, particularly genetic variations, natural selection, genetic drift, genetic migration, and speciation...
According to Charles Darwin's theory of natural selection, preferable genes are favored by nature in the gene pool, and over time, these preferable characteristics become more exclusive in the gene pool. This tutorial rounds up all the factors that can alter the makeup of a gene pool...
Certain species are capable of expressing characteristics indicative of the state of the ecosystem they occupy. They are called indicator species. Endangered species are those that face the risk of extinction. Get to know more about these species in this tutorial...
Gregor Mendel's studies into Monohybrid and Dihybrid crossing and Charles Darwin's study of evolution and natural selection have led to studies that actively manipulate the phenotype of offspring by selective breeding in animals and plants. ..
This tutorial investigates the genetic diversity in more detail. It also delineates how certain alleles are favored over other alleles in natural selection. ..
If New Zealand has lots of unique animals, it's also got a whole lot of unique plants. Find out more about some of them, and the roles they play in different natural ecosystems...
