Sexual Reproduction

• Sexual reproduction means that two parents
  combine parts of their genetic material.
• With sexual reproduction, there is usually a male
  and a female.
• The male contributes a copy of half of his
  genetic material and the female contributes a
  copy of half of her genetic material.

• The baby that is born is called the offspring.
  In a very basic way, offspring get half of their
  traits from each parent.
• Because of the way the male and female copy their
  own genetic material and the way they are
  combined, each offspring is different.
