5 Matching questions

  1. morphology
  2. adaptation
  3. genes are carried on
  4. homozygous
  5. continuous variation
  1. a a diploid organism whose chromosomes have two copies of the SAME allele. Opposite of heterozygous
  2. b chromosomes
  3. c ex: height in humans, birthweight
  4. d a FEATURE of an organism CREATED by the process of natural selection.
  5. e the form and structure of an organism

5 Multiple choice questions

  1. a hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
  2. the genetic makeup of a trait
  3. a steady state in which two or more alleles coexist in a population.
  4. the transfer of alleles of genes from one population to another
  5. 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.

5 True/False questions

  1. allopatric speciationa hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor

          

  2. polygenicmany genes?

          

  3. discontinuous variationphenotypic variation in which there are a discrete number of phenotypes with no intermediate types. Ex: pea color in Mendel's experiment

          

  4. chromosomescarries genes and appears during cell division

          

  5. natural selectionwhere a single phenotype is favored, causing the allele frequency to continuously shift in one direction
