Mendel and his peas
Gregor Mendel is a scientist that wanted to find out why his genetics are getting mixed up and find out if genetics actually got transferred from each plant.
The 1st Generation
When he did this experiment, it all came out purple flowered plants, there was no white flower as it was suppose to come out a white flower.
He decided to try and let the plants self-pollinate, and that's when he started the 2nd generation.
Pea plants preferred one trait over another in a 3:1 ratio. He predicted that pea traits like flower color were determined to separate units.
He decided to use pea plants, it said it can be the most efficient and accurate way to find out this question.
The 2nd Generation
This time, he allowed the peas self-pollinate, and it was a success. White flowers came out.
Every 3 purple flowers, 1 white flower comes out. This shows that if the peas self-pollinate, white flowers come out instead of purple flowers.
