Heredity Mendel and His Peas. Chapter 5. Heredity: the passing of traits from parents to offspring. Example: you might have curly hair, while both of your parents have straight hair or you might have blue eyes even though both of your parents have brown eyes. HOW IS THIS? Gregor Mendel:
Mendel only studied one characteristic at a time. (characteristic: a feature that has different forms in a population).
Mendel discovered that all the traits that were expressed (shown) were called dominant traits and the traits that did not show up were called recessive traits.
An organism’s appearance is known as its phenotype, what it looks like.
The inherited alleles from each parent come together to form an organism’s genotype.
In Mendel’s experiments the first generation was self-pollinated making all offspring (Pp).
