Contrast the origins of autopolyploids and allopolyploids.
What is heterosis? Discuss whether it is caused by a single geneor several genes. Discuss the two major hypotheses proposedto explain heterosis. Which do you think is more likely to becorrect?
You are interested in studying the evolution of Rnase-based gametophytic self-incompatibility. You
go into a population and identify 4 S-alleles present. These alleles are designated S1, S2, S3, and S4,
and they occur in the sporophyte only as heterozygotes at equal frequency, in each of the 6 possible
combinations:
S1 S2 S₁ S3 S1 S4 S₂ S3 S₂ S4 S3 S4
Assuming random dispersal of pollen, what fraction of S₁ pollen grains that land on stigmas will be
able to fertilize ovules in this population? Why?
