Natural Selection And The Era Of Genetics Flashcards
What was Darwin’s major problem?
Blending inheritance destroys variation and eventually everyone will look the same.
What type of genetics is Mendel?
Population genetics
What’s selection coefficient?
A measure of differences in relative fitness
Why shouldn’t individuals be nice to each other?
Other individuals will thus pass on alleles (example of Darwin’s competitive struggle)

Define reciprocy
You do this for me, I’ll do this for you…
Define cassettes of genes

Define macromutation
normally big changes in characteristics
Define dogma
