What is the definition of mainstream population?
people that share the same traits
What tends to result in a population whose individuals have extreme traits?
Directional Selection
What movements of individuals into or out of a population provides a source of?
Variation
What is the population of New Stevenston?
The population of New Stevenston is 4,108.
What is the population of New Cumnock?
The population of New Cumnock is 2,884.
How does variation lead to evolition?
Variation is caused by new genetic mutations in a population which lead to different traits in a population. Evolution selets the most useful of these mutation, eventually leading to prominence of new traits within a species or population, or even new species.
What are the effects of crossing over and other irregularities in meiosis?
The effects are mutations, which is the source of new genes and traits
What did Raymond Cattell call the underlying traits that direct surface traits?
source traits
What is Nj ranked in population?

Are source traits a set of related behaviour forms?
Source traits are a type of trait that helps to begin to form one's personality. These traits, such as extroversion, are said to be related to behavior forms.
What are the examples of source traits?
The basis or building blocks of one's personality are referred to as source traits. An example of a source trait would be someone who is outgoing or happy-go-lucky.
What will a population with different alleles have?
A population with different alleles will have traits
The traits of organisms in a population naturally change over time what is the source of the variation?
the trait that often changes after time is the size of the organism. It usually will get larger after a period of time.
What is Source-Seine's population?
Source-Seine's population is 50.
Is the source of brand new genes in a population called mutation?
Yes, brand new genes can only come from mutation.
How does environmental pressure affect natural selection?
When nothing happens to exert strong population pressure on that population, natural selection favors the allele frequency already present. When mutations cause new traits, natural selection weeds these traits out because they're not as efficient as the others.
What causes variation of traits in a population?
the enviroment.
