The presence of two identical alleles at a particular gene locus. homo=same
The process where a specific DNA pattern is obtained from a person or a sample of bodily tissue, often used in investigations.
A protein isolated from bacteria that cleaves DNA sequences at specific sites, producing DNA fragments with a known sequence at each end.
Laboratory technique for rapidly producing millions to billions of copies of a specific segment of DNA.
A technique scientists use to make exact copies of living things.
Using enzymes and various laboratory techniques to manipulate and isolate DNA segments of interest.
The use of genetic material to treat or prevent disease.
-Simple inorganic chemicals form more complex, organic ones.
-Self-replicating molecules form genetic material
-Large, organic molecules get encased within lipid droplets.
-Prokaryotic cells form
-Endosymbiosis leads to eukaryotic cells
-Multicellular organisms arise.
The development of entire groups. ex) tetrapods which are animals with four limbs.
Formation of new and distinct species in the course of evolution.
Change within a species or small group of organisms ex) mosquitoes evolving resistance to DDT.
The change in frequency of an existing gene variant in the population due to random chance.
Any movement of individuals, and/or the genetic material they carry, from one population to another.
The process by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.
How common an allele is in a population.
Provides a record of how creature evolved.
Same structures/bones but somewhat different from common ancestor.
Similar structures but not from common ancestors.
Structures that have no current purpose, ancestors used them ex) wisdom teeth
The comparison of embryo development across species.
Bipedalism, big brain, tool use
Domain of humans
Kingdom of Human
Phylum of humans
Class of humans
Humans evolved in East Africa, dispersing to populate the rest of the world from 70,000 years ago, replacing, the archaic hominins that were resident outside of Africa.
