selective breeding
No, the two terms are not synonymous. Population refers to the people who inhabit in a territory or country, whereas human resource refers to individuals comprising the workforce of an organisation. We may say that human resource of a country/state is a part of the population of the country/state, and population comprises of the human resource.
The human population of the Rockies region varies depending on the specific areas within the range. Overall, the Rocky Mountain region spans multiple states and provinces, so it is home to millions of people. Major cities like Denver, Calgary, and Salt Lake City are located within the Rockies.
Variation within societies can be caused by factors such as individual differences, cultural diversity, socioeconomic disparities, and historical events. These factors can lead to differences in beliefs, values, behaviors, and opportunities among members of a society.
the term population density measures the amount of humans in a particular are or geographical region. It can also apply to different living organisms and smaller areas.
A population's geographic distribution refers to how individuals within that population are spread out across a particular area or region. It can be influenced by factors such as habitat availability, resources, migration patterns, and human activities. Studying geographic distribution can provide insights into population dynamics, species interactions, and conservation efforts.
A variation within the population. Height in humans is an example of this.
Human species, as in the variation in height.
Variation within a population in which few or no intermediate phenotypes fall between the extremes.
The term used by biologists to describe the differences within a population with respect to features such as height is "variation". Variation refers to the range of different traits or characteristics that individuals within a population exhibit, including height.
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
Which would most likely decrease the genetic variation in the human population?
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the species.
Genetic variation must exist within the population, meaning individuals have different alleles. This genetic diversity results in a wide range of phenotypes that can be observed. Environmental factors can also contribute to phenotypic variation within the population.
sexual reproduction
Migration of individuals into or out of a population provides a source of genetic variation. This movement introduces new genes into the gene pool, increasing diversity within the population.
If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species. Google cheetah to see how this concept works.
