What is heritability coefficient?
total variation in the phenotye (IQ, introvert) that can attribute to genetic rather thatn environmental variation in the population, it is ALWAYS about groups NEVER about specific individual like Me or YOU :-)
What is relationship between blood groups and genetic drift?
Blood groups are affected by genetic drift randomly, making it special.
Is it true that there is no variation between racial and gender groups when it comes to sexual activities?
No it is not
What is the definition for Genetic Relatedness?
Genetic relatedness is a measure of the similarity of genetic material between two individuals or groups. It is used to determine the degree of genetic similarity and common ancestry between them.
In which area are the most genetically diverse populations of humans found?
The most genetically diverse populations of humans are typically found in Africa, specifically in regions with long histories of human habitation and diverse ethnic groups. This high genetic diversity is a result of Africa being the birthplace of the human species and the accumulation of genetic variation over thousands of years.
What is the accumulation of differences between groups that lead to formation of new species?
Genetic, behavioural and morphological divergence, or genetic drift.
What prevents speciation from occurring in sympatric populations?
Gene flow between populations can hinder the development of genetic differences necessary for speciation. Additionally, strong environmental pressures favoring specific traits in a population can limit genetic variation and prevent the emergence of distinct species. Lastly, hybridization between different groups can also counteract speciation in sympatric populations.
Which groups of organism use a genetic code to make proteins?
All of them!
Is genetic drift an adaptive change?
Genetic drift is considered a form of evolution. If a single population is split into two isolated groups then genetic drift will result in increasing differences over time. Eventually they will become two different species, unable to interbreed even if the two groups are brought back together.
What evidence is there to support the theory that human life came from Africa?
Genetic. The further from Africa the more the genetics have diverged, but within Africa most groups have little variation in their genetics. Using this divergence data a tree can be plotted showing when the different peoples of the world left Africa.
What causes paramyxovirus?
It's a virus, a type of pathogen entirely different from other pathogen groups. There are many different paramyxoviruses that affect humans directly, including measles, Hendra virus and Nipah virus, and mild ones that cause colds.
What is genetic deficit theory?
The view that differences in group achievement among different ethnic groups can be explained by a different genetic endowment of intellegence in those groups. In Education - if you're not Anglo-Saxon Protestant Male White...you are wrong. -___-
