,WHAT IS REPRODUCTION?

• It is the ability of organisms to
produce a new generation of
themselves ➡️this process passes on
genes and so is crucial to evolution
• You get two types: Sexual and
Asexual

• Asexual refers to the production of a
new generation by ONE parent
• Sexual refers to a new generation by
Sexual
bringing together genetic material of
two parents
