After I watched the images and read the information of the link about Meiosis and
Mitosis. I found two interesting differences between those two processes. First, in the prophase
of Mitosis, "Chromosomes begin to condense, taking on the form that they are usually depicted
in four arms connected at a point. Each chromosome is, at this time, actually two identical
copies". While in Prophase 1 Meiosis the chromosomes attach to the membrane of the nucleus
and then pair up with their corresponding chromosome. At this point Crossing over occurs in
Meiosis which does not occur in Mitosis The second is that in Prometaphase, mitosis, the "The
spindle fibers from both of the centrioles attach to each one of the chromosomes," while in
Prometaphase 1 the "Spindle fibers of each centriole attach to one chromosome of a matching
chromosome pair". This means that the fibers from centrioles attach to 23 chromosomes.

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
