Questions For David Kingsly's Holiday Lecture 2

What species is the wild relative of domestic corn?

Describe two major differences between the domesticated corn and its wild relative

What is the general term for how agriculturalists have bred modern domesticated corn or any other domesticated species?

Consider a trait (an observable feature or phenotype) that is the result of a single gene. Then consider a cross between an individual that has that trait and an individual that does not have that trait. Assume that many offspring are produced this way. What is this population referred to as?

Now consider what happens when these children mate with each other and produce offspring. What is the population referred to as?

What percentage of the F2 population would express the original trait if it was solely due to one gene?

How many genes did Beadle predict would control the major morphological differences between corn and its wild relative?

Do single genes make major contributions to the phenotype of corn? Give two examples

What are modern domesticated dogs descended from?

How long ago were they domesticated?

Describe the approach to studying the genetic basis of the major morphological features of dogs that Stocker used.

Which is best referred to as the hybrid population, the F1 or the F2?

Is the genetics of dog breeds simple or complex? Do the differences rely on many or few genes?

What was Darwin's key analogy?

What fish made it on Jeopardy from the video we watched?

What's the cost of heavy armor for a stickleback?

How are sticklebacks like salmon?

Which predator prefers sticklebacks with dorsal spines? Insects or salmon?

In Kingsley's genetic analysis of the genetic basis for body armor, what percentage of the variation in plate number was a single gene responsible for?

What experiment was key for showing that this gene played a significant role in body armor production?

Which fish are more likely to have completely developed pelvic fins (Marine or Freshwater), and what advantage do these fins provide to the stickleback?

How can evolution progress so fast - in just 10,000 years unarmored sticklebacks have evolved in many environments for example. Give two components.
