- Great Chain of Being: a classificatio created by Aristotle; a hierarchy; a fixity- things do not change
- Classification: Carolus Linnaeus created binomial nomenclature- formal sys. of naming species with each name composed of 2 parts; taxonomy- classification of organisms based on similarities
- Cladistics: ancestral (a long time common ancestor) v. shared-derived (what makes certain groups unique); ex) Occam's razor
- Cuvier: catastrophism
- Lyell: uniformitarianism
- Lamarck: inheritance of acquired characteristics; girraffe's
- Malthus: population can only grow as long as their environment will allow them
- (1) The tendency of individual genetic characteristics in a population to vary from one another.
- (2) The potential of a genotype to change or deviate when exposed to environmental or genetic factors.
- more differences in population than compared to the outside
- need a selective pressure in environment = an environmental change
- a genetic variation (massive change over a long period of time)
- produce a difference with the ability to reproduce
the ability to produce more offspring with the same adaptations as the parents, allowing the species to survive under changed environmental conditions
- Deoxyribonucleic acid
- the genetic material consisting of a complex molecule whose base structure directs the synthesis of proteins

- everyone has two alleles for each trait (one from each parent)
- Homozygous: XX
- Heterozygous: XY

- the entire set of genes in an organism
- what we look like
- due to genes and environment
- ex) skin color, height, behavior
- process of conversion of RNA instructions into proteins
- tRNA-> amino acid->polypeptide chain-> creates protein
- The process follows transcription in which the DNA sequence is copied (or transcribed) into an mRNA.
It is the process of transcribing or making a copy of genetic information stored in a DNA strand into a complementary strand of RNA (messenger RNA or mRNA) with the aid of RNA polymerases.
- A kind of cell division that produces the sex cells, each of which has half the number of chromosomes found in other cells of the organism
- haploid: half the number of chromosomes
- A kind of cell division that produces new cells having exactly the same number of chromosome pairs, and hence copies of genes, as the parent cell.
- diploid: same number of chromosomes
- in the cell's nucleus, the structures visible during cellular division containing long strands of DNA combined with a protein
- dark bands: genes/alleles

- messanger RNA
- single stranded
- Abbreviated form for messenger ribonucleic acid, the type of RNA that codes for the chemical blueprint for a protein (during protein synthesis)
- transfer RNA
- RNA involved in protein synthesis, i.e. transporting specific amino acid to the ribosome to be added onto the growing polypeptide chain
In biology, a group of similar individuals that can and do interbreed.
- demonstrates algebraically that the percentage of individual that are homozygous for the dominant allele, homozygous for the recessive allele, and heterozygous should remain constant from one generation to the next, provided that certain specified conditions are met.
- understand if a population is at equillibrium
- no variation, stable, not evolving unless by an outside force
In genetics, mutation may be small scale (affecting the nucleotide sequence of a gene) or large scale (involving a change in the chromosome). It may arise from faulty deletions, insertions, or exchanges of nucleotides in the genetic material, as caused by exposure to ultraviolet or ionizing radiation, chemical mutagens, viruses, etc. Such a change may result in the creation of a new character or trait.
- The process of change in the genetic composition of a population due to chance or random events rather than by natural selection, resulting in changes in allele frequencies over time.
- Founder Effect: The establishment of a new population by a few original founders (in an extreme case, by a single fertilized female) which carry only a small fraction of the total genetic variation of the parental population
- Bottleneck: wipes out millions of people in a short period of time. ex) plague, natural disaster
- Gene Flow: the movement of genes from different populations of species. ex) migrating
- Natural Selection: changed by the enviromnent
- Non-Random Mating: ex) sperm donor; share religion; attraction
- An abnormalityin the formation of red blood cells caused by a mutation on chromosome eleven that is responsible for the production of functional haemoglobin.
- Blood can't carry oxygen
Define natural selection as part of evolution, and other influences on the process.
- Natural selection occurs during an environmental change. It affects a population and the change occurs over a long period of time.
- The 3 keys to natural selection are 1) a selective pressure in the environment 2) some sort of genetic variation 3) and produce a difference that is able to reproduce.
- artificial selection: forced by humans; ex) domesticated plants and animals
Explain evolutionary processes which lead to variation.
- Genetic drift: change in genetic composition of a population due to random events
- Founder Effect: a new population by a small group
- Bottleneck: millions die in a short period of time
- Gene Flow: ex) migration

- Ribosomes: A minute particle composed of protein and ribonucleic acid (RNA) that serves as the site of protein synthesis.
Show how DNA is the blueprint for life.
DNA is said to carry the genetic ‘blueprint’ since it contains the instructions or information (called genes) needed to construct cellular components like proteins and RNA molecules.
Outline process of protein production and genes.
- Transcription: making a copy genetic info stored in a DNA strand; occurs in the nucleus
- Translation: the process follows transcription in which the DNA sequence is copied into an mRNA; creates protein
Describe and compare meiosis and mitosis.
- Meiosis: 2 daughter cells become 4 daughter cells = haploid: half the number of chromosomes
- Mitosis: only has 2 daughter cells = diploid: the same number of chromosomes
Identify chromosomes and karyotypes.
Describe cell division and problems associated with it.
- The separation of one cell into two daughter cells, involving both nuclear Division (mitosis) and subsequent cytoplasmic division (cytokinesis).
- The process in reproduction and growth by which a cell divides to form daughter cells.Also known as mitosis and meiosis. Mitosis is cell replication, where two cells that are an exact copy of their parent cell are created. Meiosis is where four gamete cells are created from the parent cell, with half the chromosome compliment.
- Issues: splitting of cells may have uneven chromosomes; ex) down syndrome and miscarriages
Describe the difference between population, polytypic, and subspecies.
- population: a group of similar individuals
- polytypic: describes the expression genetic variants in different frequencies in different populations of a species
- subspecies: a taxonomic group that is a division of a species; usually arises as a
- consequence of geographical isolation within a species.The most precise classification of organism. Our own species, Homo sapiens sapiens is a prime example of a subspecies, which over time had diversified from Homosapiens and respective common ancestors.
The study of genetic influences on the components of cause and effect in the somatic characteristics of populations.
The smallest working unit in the system of classification. Among living organisms, species are populations or groups of populations capable of interbreeding and producing fertile viable offspring.
Explain the idea of polymorphisms and explain why it's important.
- The occurrence of more than one kind or form of organisms of the same species that exist together in one locality.
