Question 1

Gregor Mendel's law of independent assortment argues that:

Accepted Answer

A) pairs of genes separate during reproduction and are passed on to the next generations without being altered (they remain distinct). 
B) different genetic traits are inherited as separate qualities (they are not dependent on each other). 
C) inheritance is particulate and not blended (they come in pairs and are passed intact). 
D) heredity occurs only during meiosis (mitosis is not associated with heredity). 
E) genes are exchanged between parents at the moment of conception.
