Q: It seems that developmental genetics boils down to a complex network of

It seems that developmental genetics boils down to a complex network of gene regulation. Try to draw a structure of this network for Drosophila. How many genes do you think are necessary to complete t...

Q: At the molecular level, how do you think a gain-

At the molecular level, how do you think a gain-of-function mutation in a developmental gene might cause it to be expressed in the wrong place or at the wrong time? Explain what type of DNA sequence w...

Q: Discuss examples of positive and negative assortative mating in natural populations,

Discuss examples of positive and negative assortative mating in natural populations, human populations, and agriculturally important species.

Q: Discuss the role of mutation in the origin of genetic polymorphisms.

Discuss the role of mutation in the origin of genetic polymorphisms. Suppose that a genetic polymorphism involves two alleles at frequencies of 0.45 and 0.55. Describe three different scenarios to exp...

Q: Most new mutations are detrimental, yet rare beneficial mutations can be

Most new mutations are detrimental, yet rare beneficial mutations can be adaptive. With regard to the fate of new mutations, discuss whether you think it is more important for natural selection to sel...
