Antibiotics

What are used to fight infections? Answer with a single words or term.

Evolution

________ tends to happen when migration operate.

microevolutionary factor

What is sensitive to population size? Answer with a single words or term.

Genetics

________ can be altered by inbreeding and an individual may be a clone of a given gene.

Individuals

________ move between populations with selection.

Phenotypic distribution

What is not usually favored by such alleles? Answer with a single words or term.

Creveld syndrome

Who is a form of dwarfism? Answer with a single words or term.

Kimura

________ says that the majority of variation in the DNA sequence is due to high frequencies attained in a population via genetic drift.

Sexual selection

What is a form of natural selection in which people with certain characteristics are more likely than others to have successful reproduction? Answer with a single words or term.

Population geneticists

Who are interested in the genetics of selection? Answer with a single words or term.

Population genetics

________ is the study of genes in a population.

Lancaster County population

The ________ can be traced to one couple, one of many generations, according to evidence.

Heterozygotes

________ tend to be more sexual than Homozygotes.

Genetics

________ contribute to the genes of the next generation and inbreeding alone does not affect them.

Kimura

________ said that genetic drift promotes neutral variation and that it is more important in smaller populations than in larger ones.

Population geneticists

________ can evaluate the extent of migration mating by looking at the similarities and differences of the two populations.
