Construct a chart to contrast mitosis and meiosis. include the following:
a. the number and type cells produced
b. the number of replications of dna
c. the number of actual divisions of cells
d. the formation of tetrads (pairs of homologous chromosomes)
e. the use of the terms diploid and haploid in the resulting cells

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species
