Question #1
Describe how both growth and development depend on the cell cycle. How do these outcomes
differ and how are they the same? Your description and explanation should include how genes
and chromosomes are involved.
Post your primary response and support your statements with references. Your primary post
should be at least 125 words or so.
Question #2
The trillions of cells in your body originated with a fertilized egg. In order to develop and grow, the
somatic cells experienced mitosis, while the gametes, specialized for reproduction, are the result
of meiosis.
Two different processes of cell division, meiosis and mitosis, have evolved over time. Both of
these are involved in cell division, but their results are distinctly different. Explain how the
processes of meiosis and mitosis differ and how the outcomes are different. Offer an explanation
why two different processes are needed. Post your primary response and support your
statements with references. Your primary post should be at least 125 words or so.
Question #3
An organisms phenotype is determined by its genotype. The genotype is inherited from its
parents and the phenotype may be shaped by environmental influences. For example, an
individual may have inherited genes that would lead to being taller than average. However, if the
individual does not receive proper nourishment, then the influence of the genes may not be fully
realized and the individual may be shorter than average.
Pick a trait that you can see in either a plant or animal. Explain how the alleles determine the
phenotype for that trait and then describe how the environment might influence the phenotype.
Please try to use a specific example that is not already explained.
