A DNA sequence that recognizes
Methylated DNA and hypoacetylated certain transcription factors that can
nucleosomes stimulate transcription of nearby
genes.
blocks fertilization
f(aa)= 26/6000 = 0.0043
examples: geographic barriers,
f(a)= sqrt(0.0043) = 0.0658
temporal isolation, behavioral
f(A)= 1 - 0.0658 = 0.934
isolation, mechanical isolation,
f(Aa)= 2(0.934)(0.0658) = 0.123
gamete isolation
