Question

Throughout a species distribution, increasing connectivity will potentially: Increase gene flow Have an epistemic effect Increase random genetic drift Increase co-adapted gene complexes It will cause the fixation of new alleles Where O = observed values and E = expected values, the chi square statistic is calculated as: x^2 = sigma (O-E)/E x^2 = sigma(E - O)?O x^2 = sigma(E-O)?E x^2 = E(O-E) None of these Selection involving which of the following creates an equilibrium in which different alleles are retained in a population despite their being harmful in homozygotes? A) Directional selection B) selection C) Stabilizing D) Balancing selection E) None of these Divergent selection on genitalia in animals can result in reproductive isolation. A potential mechanism driving this form of selection is: A) out breeding depression B) speciation C) Synonymous speciation D) Inbreeding depression E) Homologous speciation

Explanation / Answer

32. A. Increase gene glow

33. E - None of the above
x2 = E (O-E)2 / E

34. D - Balancing selection
It involves heterozygote superiority creates a dynamic equillibrium it makes different alleles are retained in population there being harmful in homozygotes.

35. Outbreeding depression
