BIO 133 EXAM 2 QUESTIONS AND ANSWERS
Example of a mulitfactorial trait - Answer -alzheimers
Genetic determinism is the idea that... - Answer -our genes soley determine who we
are at every level, including physical, emotional, and behavioral
Example of genetic determinism.. - Answer -a person using genetic determinism as his
defense in a murder trial
What is responsible for variation in organisms - Answer -gene and the environment
Mendelian traits - Answer -trait due to single gene
Multifactorial traits - Answer -traits influenced by environment
Polygenic traits - Answer -is one whose phenotype is influenced by more than one
gene. Example height, skin color. Many polygenic traits are also referred to as
quuantitative trait loci.
Empiric risk refers to the - Answer -prediction of recurrence based on trait's incidence in
specific population
Incidence - Answer -rate at which event occurs
Prevalence - Answer -number of individuals who have a disorder at a specific time
Heritability - Answer -% of phenotypic variation due to genes.(know how to cal the
heritability).
