Concept 1Children resemble their parents.

factoid Did you know ?

Aristotle (384-322 B.C.), the Greek philosopher, thought that inheritance was not a spirit or an emotion but a physical substance coming from both parents. He also thought that the giraffe was a hybrid animal, the result of a cross between a leopard and a camel.


Why aren't there naturally occuring hybrid animals like a leopard camel cross?

Hello, I'm Gregor Mendel. I worked with pea plants because they are easy to grow and they have many variable traits. Most importantly, they can be crossed with themselves or other pea plants. When left alone, pea flowers self fertilize. Let's look inside...The stamens, the male sex parts, mature first and drop pollen inside the immature flower. The pistil, the female sex part, matures later. Its eggs are fertilized by the pollen that lands on the pistil. To cross fertilize pea plants, I opened the immature flower. Then, I cut off the stamens before they matured and dropped pollen. After the flower matured, I dusted its pistil with pollen from another plant. This is cross fertilization.
