5 Matching Questions
- balanced polymorphism
- character displacement
- a the result of competition between two species that causes the members of different species to become morphologically or behaviorally more different from each other
- b the process of division of normal body cells through which new diploid cells are created
- c a steady state in which two or more alleles coexist in a population.
- d many genes?
- e where two somewhat related species eventually form a new species
5 Multiple Choice Questions
- phenotypic variation in which there are a discrete number of phenotypes with no intermediate types. Ex: pea color in Mendel's experiment
- driving force behind sympatric speciation extreme values for a trait are favored over intermediate values. E.g.: large nose rather than medium sized nose
- where a single phenotype is favored, causing the allele frequency to continuously shift in one direction
- the transfer of alleles of genes from one population to another
- the process of cell division in which haploid gametes (eggs and sperm) are creatred
5 True/False Questions
gradualism → opposite of punctuated equilibrium
stabilizing selection → 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.
sympatric speciation → a hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
microevolution → evolution of new species, families, and higher taxes
diploid → the process of division of normal body cells through which new diploid cells are created
