- b states that individuals are members of the same species if they are capable of interbreeding and producing viable/fertile offsrping
- c type of selection favors individuals at opposite ends of the phenotypic range
- d condition where there are two or more versions of a trait within a population
- e movement of genes from one population to another due to the input of genes from individuals of another population
5 Multiple choice questions
- selection can only act on _________ variation
- NO variation means....
- Natural selection acts on _______ but evolutionary change ultimately implies change in the _______ of the population
- the biological species concept might not work for _______ organisms
- a post-zygotic barrier where fertilization occurs but the hybrid offspring do not survive well, either in the womb or after birth
5 True/False questions
temporal isolation → pre-zygotic factor that prevents breeding because of different mating areas or places
macroevolution → variation in heritable traits within a population plus differential survival/reproduction = change in traits in a population over time
Hutton → change in in structure of a gene or chromosome, only way to create new alleles
speciation → creation of new species
small → what kind of population experiences an increase in drift?
