qualitative or categorical 
affected little by environment 
 
Quantitative Correct Answer: measured with numbers 
 
Polygenic Traits Correct Answer: Affected by many genes with no gene having an overriding influence. 
- EX: Growth rate, milk production, ribeye area 
Typically quantitative or continuous in expression.
