142 wild wild males
52 wild ebony males
46 dumpy wild males

What pattern of inheritance is observed for body color?
Autosomal recessive
Autosomal dominant
Sex-linked recessive
Sex-linked dominant
What are the genotypes of the parents in the P generation?
a.
XBYdd x XbXbDD
b. Bbdd x bbDd
c. BBdd x bbDD
d. BBX Y x bbXDY
How many flies in the F2 generation would you expect to express the dumpy wild phenotype?
a.
289.125
b. 97
c. 96.375
d. 293
4. This question focuses on entrainment.
a. What is entrainment?
b. What environmental cues are involved in entrainment, and which one is most influential?
c. Why is entrainment necessary?
d. Assuming that a flash of darkness is an effective zeitgeber, what impact on circadian
rhythms would you expect to result from an event such as the 2024 solar eclipse (assume
it was viewed from Carbondale IL, where totality occurred at about 2 pm)? Explain your
reasoning. You may wish to consult this phase response diagram.

e. Finally, give a real-world example of how knowledge of circadian rhythms and
entrainment has implications for human health and wellbeing or conservation biology.
This example could be from your reading or from things discussed in class.
Generate one question that requires a Punnet Squre to solve the question. Then show how you calculate the possibilities of genotype and phenotype
