How does this happen?
What this lesson covers

Mixing instructions
In sexual reproduction instructions from two parents combine to create offspring that are not exactly like either parent. They share some traits with both parents but also have differences. This mixing helps keep useful features while allowing new ones to appear.
Sexual reproduction: instructions from two parents (male and female) combine. Offspring share traits with both but are not exactly like either. This keeps useful features and lets new ones appear.
Notes
