become friends with the organism
19
If nondisjunction occurs,
a gamete will receive too many or too few chromosomes.
no gametes will be produced.
mitosis cannot take place
there will be too many gametes produced.
20

have had all their genes removed
are always evil
only include corn
21
A pedigree is
