Mendel's 2nd law, which states that factors controlling different characteristics are inherited independently of one another is called the law of:
a)
Judge Dredd
b)
independent assortment
c)
segregation
d)
domination
14.
Mendel's 1st law says that there are 2 factors controlling a given characteristic, one of which is dominant and one which is recessive, and these factors separate and go to different gametes during meiosis. This law is shortened to just be called the law of:

separation
b)
segregation
c)
flatulation
d)
inheritance
