DI - Mendel’s results
Mendel worked with true-breeding plants
When these self-pollinate, they may offspring that match the parent
He cross pollinated true-breeding purple with true-breeding white.
The offspring are hybrids.
Offspring produced from parents with two different forms of a trait.
They were all purple.
But, they were different from the parents.
They had information from both a purple plant and a white.
What would this cause?
Mendel crossed the purple hybrids
The white flowers re-appeared in the offspring about 1/4 of the time.
This result was consistent every time he crossed hybrids.
It worked with other traits the peas had as well.
Mendel experimented with seven different traits.
Whenever he crossed hybrids, one form of each trait appeared about 3x more often than its other form.
He labeled these traits “dominant” and “recessive.” How did he decide which was which?
What human traits seem to behave this way?
What does this all mean?
