Gregor Mendel was an Austrian Scientist, that published a book, where he listed all the observations on his experiments. What he basically did, was that he crossed pea plants, and made a theory on inheritance. Using punnet squares and thousands of repeating experiments he conducted, he came to the end, and proved the theory.
Key Words
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.
