Q
whats continuous variation
A
variation the shows a complete range with no distinct groups (full range)
controlled by polygenes (several genes) and environmental factors
2
Q
whats discontinuous variation
A
variation with distinct groups or categories, variation caused by one gene, qualitative eg eye or hair colour, usually in the form of a bar chart
3
Q

A
a normal distribution curve, bell shaped and symmetrical around the mean
