Genetic drift is caused when breeders are not representative of the population as a whole
Large population size is necessary for evolution by natural selection
Genetic drift operates more strongly in small populations

A gene for leaf shape in morning glories has a dominant (T) and a recessive allele (t) with the
following frequencies T = 0.5, and t = 0.5 and a population of 100 individuals. After sequencing

for each genotype:
20 TT
65 Tt
