Two genes are linked. One gene affects fur color (B is black and b is grey). The other gene affects fur length (H is short fur and h is long fur). An individual has the genotype BbHh.  If this individual reproduces sexually, we would predict that the B and b alleles [a] the alleles for fur color and fur length [b] Mendel was not able to observe cellular processes, but we now know that the way [c] works provides the mechanism behind both of Mendel’s laws. 

In a species of Pokemon, individuals can be either blue or red. Color is coded for by a single gene with two alleles – one allele codes for blue and another codes for red. A pair of Pokemon – blue female and red male – start a family. The pedigree showing their descendants is given above. Circles are XX females; squares are XY males. Shaded individuals are red; unshaded individuals are blue. Carriers (if any) are not shown. Red appears to be [b] to blue. The gene that determines blue vs red color appears to be [a]. If this were a real species that originally had only the blue allele, why would the allele for red color have appeared? [c]  To any Pokemon nerds: I realize that I am probably violating Pokemon canon in some way with this question; apologies. My son also informs me that the red phenotype is called “shiny”, but that is seriously confusing to anyone who’s not already familiar with Pokemon, so we’re calling it red (which is what it looks like) for this question.

A type of flowering plant lives for over 50 years. A large number of the plants are growing in an area. For the first 10 years of their lives, they produce pink flowers. During years 10-20 of their lives, acid rain increases, and the soil pH changes from 7 to 5. In years 20-50 of their lives, the plants produce purple flowers. The change in pH from 7 to 5 resulted in a [y] in hydrogen ions in the soil. The most plausible explanation for the change in flower color of the plants is [x].

Before you submit your exam, hold up your notes page & scratch paper for the camera again. You’ll need to submit pictures of them in the final assignment in this module in order to complete the exam work. Thank you for all your hard work this semester! I have enjoyed working with you, and I hope to see you again in a future course. Have a wonderful summer!

Production of a chemical in an insect species is controlled by one gene with two alleles. HH and Hh produce the chemical, hh individuals do not. The group of insects is currently very large, with about half the individuals producing the chemical and have not producing it.  Researchers determine that production of the chemical attracts a predator of the insects. Insects that produce the chemical are 75% more likely to die than insects that do not produce the chemical. Chemical production has no impact on the number of offspring produced by an insect that survives to adulthood. Based on this information, what is our best prediction for this insect species? The H allele and ability to produce the chemical will __________________.
