His experimental design was made to compare two types of peas and the generations after to discover dominant and recessive traits. He learned that the round, green, and long peas dominated the angular, yellow, and short peas. Mendel saw that there were some yellow peas in later generations
Scientists believed Mendel was just going over already known information of genetics, it wasn't until years after Mendel's death that scientists were beginning to understand his tests. At the time of the experiment's release Mendel didn't even understand it.
His tests were able to be used for other things which had data that was consistent with the data Mendel had come up with. Which helped scientists find out more about inheritance.
Dominant-Gene that will overpower another gene
Recessive-Gene that gets covered up by a dominant gene
Example- Blue eyes
Co-Dominant-Gene that is neither dominant or recessive
Straight hair and curly hair
