- allopatric speciation
- stabilizing selection
- bottleneck effect
- a selection pressuresd that favor average phenotypes. Stabilizing sleection reduces the amount of variation in the population but doesn't alter the mean value of the trait.
- b speciation that occurs when two or more populations of a single species are geographically isolated from each other and then diverge to form two or more new species
- c occurs when a population endures a natural disaster and alleles are greatly reduced in diversity
- d refers to cells that have pairs of homologous chromosomes, where one chromosome of each pair is inherited from each parent. All primates are diploid
- e a gradual transformation of one species to another
5 Multiple choice questions
- genes that influence multiple traits
- evolution of populations within a species
- two-step process in speciation where selection causes the differentiation of geographically separate, isolated populations of a species and the populations become reproductively isolated as well
- a hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
- the shown trait
5 True/False questions
adaptation → a spontaneous change in the chemical structure of DNA
What are the differences between DNA and RNA → DNA is double stranded while RNA is single stranded, DNA has only a nucleus but RNA can have a nucleus or a cytoplasm, the main ingredient in DNA is Thymine while in RNA it's Uracil.
balanced polymorphism → a steady state in which two or more alleles coexist in a population.
natural selection → where a single phenotype is favored, causing the allele frequency to continuously shift in one direction
polygenic → the evolutionary relationships among a group of species. diagrammed as a family tree
