- What are the differences between DNA and RNA
- disruptive selection
- sympatric speciation
- a the genetic makeup of a trait
- b a hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
- c 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.
- d driving force behind sympatric speciation extreme values for a trait are favored over intermediate values. E.g.: large nose rather than medium sized nose
- e one of two or more alternative forms of a gene
5 Multiple choice questions
- 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
- refers to cells that have pairs of homologous chromosomes, where one chromosome of each pair is inherited from each parent. All primates are diploid
- genes that influence multiple traits
- the result of competition between two species that causes the members of different species to become morphologically or behaviorally more different from each other
- the process of division of normal body cells through which new diploid cells are created
5 True/False questions
adaptive radiation → a FEATURE of an organism CREATED by the process of natural selection.
founder effect → occurs when a new colony is started by a few peope from the original population. Not much diversity, usually mutations.
directional selection → driving force behind sympatric speciation extreme values for a trait are favored over intermediate values. E.g.: large nose rather than medium sized nose
genes are carried on → chromosomes
genetic drift → the transfer of alleles of genes from one population to another
