penetrance - Percent/degree to which a dominant allele expresses itself
meiosis - involves reduction division
haploid cell - N; gametic condition
lethality - Particular Mendelian violation-- ratio contains a '0' e.g., 9:4:0

Pleiotropy - The impact of a single gene on many traits is...
dopamine - Huntington's disease, Parkinson's disease and cocaine usage are all related to the
body's use of the molecule known as...
all of the above (normal distributions, a wide-ranging trait variability, and quantitative traits with
ratios from Pascal's triangle) - Cumulative interaction generates...
