The result is a seed. Heredity Plants inherit characteristics from their parents in the same way animals do. The laws of heredity explain why different traits herited by offspring of the same parents. Moreover, these laws it possible to predict the number of offspring that will inherit a certain trait. A knowledge of the laws of heredity is essential for effective plant breeding.
All cells contain genes, which are the units that determine raits of a plant or animal.
The cells have only one gene for each trait. Of the thousands of germ that a plant produces, about half have one of the genes for each and about half have the other gene. When the male and female germ cells unite in the ovule each contributes one gene for each trait so that the new seed then has two for each trait. The various combinations of the many genes inherited from the pollen parent and from the seed parent determine traits of the offspring and of future generations. You can't tell by looking at a plant exactly what genes it contains.
