Document Summary

This leads to a buildup of these fluids particularly in the respiratory system. How are these passed? g. incomplete dominance: the case where a heterozygous does not look like the homozygous dominant individual. Iheterozygote looks different that either homozygous individual ii. Topic 10 evolution: definition of evolution a. macroevolution b. microevolution, 3 phases of evolution, general idea of what happens in each big picture items, no years, endosymbiotic theory a. Biological evolution: characteristics, charles darwin, who was he, where did he study iii. origin of species, natural selection, survival of the fittest what is fitness (giraffe example)?? ii. Queen iii. modes directional, disruptive, stabilizing: balanced polymorphism and heterozygote advantage b. mutation, must be in the sex cells to be heritable c. nonrandom mating, sexual dimorphism ii. Big picture concepts: archeological evidence (fossils, biological evidence (distribution, anatomical evidence (common features of different organisms, biochemical evidence (atp, amino acids, dna, etc. , skin color distribution a.

13. Meiosis differs from mitosis in that:
a. meiosis results in the production of two new cells, whilemitosis results in the production for four new
cells., b. meiosis is used for growth and repair, while mitosis isused for production of eggs and sperm., c.
cytokinesis can be unequal following meiosis, but is approximatelyequal following mitosis., d. meiosis
involves one cell division, while mitosis involves two celldivisions., e. meiosis results in the production of
diploid cells, while mitosis results in the production of haploidcells.

synapsis of meiosis I. This process is called:
a. crossing over., b. random mating., c. random fertilization., d.random shuffling of parental
chromosomes.,

a. all young are genetically identical to the parent., b. malesmust evolve a copulatory organ., c. genetic
variability in the population is increased., d. females must evolvea vagina., e. mates are not needed.
