Pea Pollination

Important words from the text

Heredity= The passing of physical characteristics from parents to offspring

Trait= a characteristic that an organism can pass to its offspring through its genes.

Genetics= the scientific study of heredity.
Fertilization= the process where a new organism begins to form when egg and sperm join.

Purebred= organism is the same offspring of many generations that have the same trait. 

Hybrid= organism that has mixed, different traits.

Crossing Pea Plants

1. To prevent self-pollination, Mendel removed the pollen-producing structures from a pink flower.

2. He used a brush to remove pollen from a white flower to another plant. He brushed this pollen onto the pink plant.

3. The egg cells in the pink flower were then fertilized by sperm from the white flower. After a time, peas formed in the pod.

4. Then you get the crossing of pollination. 

Samples

I think that Mendel would have to take 1000 samples for each plant to get a very accurate estimate to see what the pollination of pea plants.
