Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Mitosis results in two identical diploidcells. What structures form during prophase?
With regard to thickness and length, what do you think chromosomes would look like if you microscopically examined them during interphase? How would that compare with their appearanceduring metaphase?
EVOLUTION CONNECTION The result of mitosis is that thedaughter cells end up with the same number of chromosomesthat the parent cell had. Another potential way to maintain thenumber of chromosomes would be to carry out cell divisionfirst and then duplicate the chromosomes in each daughtercell. Assess whether this would be an equally good way oforganizing the cell cycle. Explain why evolution has not ledto this alternative.
In the mitosis experiment, in what stage were most of the onion root tip cells in? Based on what you know about cell cycle division, what does this imply about the life span of a cell? Were there any stages of the cell cycle that you did not observe? How can you explain this using evidence from the cell cycle?
A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cells in metaphase, 7 cells in anaphase, and 5 cells in telophase. If the complete cell cycle requires 24 hours, what is the average duration of the M phase in these cells? Of metaphase?
In mitosis, what chromatid combination(s) will be present during metaphase? What combination(s) will be present at each pole at the completion of anaphase?
