A
What is the term for a change capable of being passed on to the next generation?
heritable change
What is the range of genes and all their alleles present in a population called?
gene pool
What is the term for the change in the genetic composition of a population during successive generations, which may result in the development of new species
Evolution
True or false?
Individuals in any population express a range of different phenotypes, caused by variation in their genotypes.
True
What is the term for the transfer of alleles that results from emigration and immigration of individuals between populations?
gene flow
What is the term for the change in the gene pool of a population as a result of chance and which usually occurs in small populations?
genetic drift
What is the term for a type of gene flow that occurs when a few individuals that have become isolated from a larger population do not carry all the alleles that were present in the original population?
Founder effect
What is the term for the effect when a catastrophic event or a period of adverse conditions drastically reduces the size of a population, reducing genetic variation within the population?
bottleneck effect
What is the process called where a small scale variation of allele frequencies within a species or population, in which the descendant is of the same taxonomic group as the ancestor occur?
microevolution
What is the process called where the variation of allele frequencies at or above the species level, over geological time, resulting in the divergence of taxonomic groups, in which the descendant is in a different taxonomic group from the ancestor occurs?
macroevolution
