Meiosis
-
Gametes only have one copy of each chromosome - offspring get full amount of chromosomes as a result of this!
Steps of Meiosis

There are 4 different types of bases called Adenine, Thymine, Cytosine and Guanine (A,T,C,G for short)
-
A always pairs to T because they are paired by two hydrogen bonds whereas C always paris to G because they have three hydrogen bonds between them
