Check and Challenge CH16

Chapter 16 Check & Challenge


1. This would be more likely to produce Micro Evolution as it will affect individual organisms rather than big groups of organisms.
2. Gene pools are all the possible genes in a species while allele frequencies are for individual environments.
3. Gene pools are more localized and so they must be relating to populations rather than to species.
4. Mutations affect a species really quickly while genetic recombination takes time.
5. It predicts that the allele frequencies will stay the same over time.



1. It is the most important in the small populations as it has a bigger effect the fewer amount of organisms present there.
2. The main forces that affect gene pools are natural selection as it is when organisms with weak adaptations are eliminated and organisms with strong adaptations survive.
3. It has the same chance of occurring each time but it increases exponentially to happen more than once.
4. The studies of twins are more important for studying quantitative traits as there are many alleles which may affect these.
