Unformatted text preview: Justin Fitzgerald Study Guide Chapter 5 Antibody- a substance that reacts to other substances invading the body (antigens) Antigen- a substance invading the body that simulates the productions of antibodies Electrophoresis- a lab method that uses electric current to separate proteins, allowing genotype to be determined Restriction Fragment Length Polymorphism (RFLP) - a genetic trait defined in terms of the length of DNA fragments produced when certain enzymes cut the DNA sequence Micro satellite DNA- Repeated short sequences of DNA; the number of repeats is highly variable Alu insertions- a sequence of dna repeated a differnt locations on diff. Chromosomes. Mitochondrial DNA-A small amount of DNA that is located in the mitochondria of cells Mitochondrial DNA is inherited only through the mother. Anthropometrics- measurements of the human body, skull, and face Odontometrics- measurements of the size of feet Dermatoglyphics- measurements of finger and palm prints, including type classification and ridge counts Race- referring to group membership Admixture- Typology Demography Univariate analysis Multivariate analysis Genetic distance- an average measure of relatedness between populations based on a number of traits. Its used for understanding effects if genetic drift and gene flow which should affect all loci to the same extent. Genetic distance map- a picture that shows genetic relationships between populations, based on genetic distance measures. Justin Fitzgerald Study Guide Study Questions 1. What is micro satellite DNA? Repeated short sequences of DNA; the number of repeats is highly variable 2. What is mitochondrial DNA, and how is it inherited? A small amount of DNA that is located in the mitochondria of cells. Mitochondrial DNA is inherited only through the mother. 3. What are anthropometrics? measurements of the human body, skull, and face 4. What are the problems with the biological concept of race in analyzing human biological variation? You should focus specifically on issues concerning the number of races and the nature of continuous variation. Problems arise because of the two different approaches to race cultural and biological -- do not always match up or even overlap one another. 5. Does human skin color show a continuous distribution, or do humans come in several distinct "shades?" 6. How does genetic variation within races compare to genetic variation among races?...
