1

What did scientists believe about offspring before Mendel

That variations in parents blended or fused together in their offspring

2

How did Mendel do to test genetics

Observed characteristic in pea plants
He bread pea plants together by using a paintbrush from one plant to the flower of another plant. A bag was then placed over the flower on the pant and sealed. He planted the seeds that were formed and observed the characteristics of the offspring

3

Mendel genetic laws

1 a pair of alleles will separate when gametes are formed
2 inheritance is random
3 in each pair of allele one is dominant and one is recessive. The dominant is always expressed over the recessive

4

From models experiments what did he conclude

Inherited factors control the variation of characteristics. The factors exist in alleles and don't change

5

Why was menedels work ignored

Scientists did not see how factors could explain the many variations in characteristics or how his ideas could explain evolution
