A$.$ back mutation

B$.$ founder effect

C$.$ mutation

D$.$ heterozygote advantage

E$.$ genetic drift

F$.$ natural selection

G$.$ gene flow

H$.$ genetic diversity

I. bottleneck effect

J$.$ non$-$random mating

$1.$ degree of variation within a species or a population

$2.$ permanent change in the DNA molecule; a change in nucleotide sequence; gene position, gene loss, insertions, deletions, etc.; has the potential to affect an entire gene pool.

$3.$ net movement of alleles from one population to another due to migration of individuals and subsequent interbreeding

$4.$ mate selection during breeding based on phenotype $($strength$,$ speed, aggressiveness$)$; also caused by inbreeding

$5.$ loss of alleles from a gene pool as a result of some individuals not breeding; a change in allele frequencies due to chance events in small populations

$6.$ gene pool change that results from a rapid decrease in population size

$7.$ gene pool change that occurs when a few individuals start a new, isolated population $($such as on an island$)$

$8.$ only process that leads directly to evolutionary adaptation; individuals with certain inheritable traits survive specific local environmental conditions, and through reproduction, pass their traits on to offspring

$9.$ for example; the genotype Cc in cystic fibrosis may help resist diarrheal diseases such as cholera

$10.$ mutation that reverses the effects of former mutations
