Intro to Genetics - Lesson and Notes

Poll

What do you think the offspring will look like?

• In between like a light purple color

• Some offspring plants will be purple and others will be white

• All purple

• All white

Poll

What do you think???

Will the next generation be ALL purple?

• Yes, both parents are purple, so all the new pea plants will be purple.

• No, some might be white
