Gregor Mendel

• Gregor Mendel helped us understand genetics
• 1st set:

  Mendel crossed a tall pea plant with a small pea plant and found that all the offspring were tall.

  2nd set:

  Mendel took 2 of the offspring from the first set and crossed them. This time 75% of the offspring were tall, and 25% small. This proved that the offspring produced in the 1st set were heterozygous
• Mendel discovered that genetics were passed from each parent to their offspring
