In class we did an online lab about dominance. Here is the link:

After crossing many different pea plants, snapdragons and lentils, I realized that there are three types of dominance.
The first type is dominance. This is when the dominant allele is completely dominant over the recessive allele. For example pea plants. We can see the dominant gene in color. There are two colors of pea plants; purple and white. The purple is dominant over the white. If one parent is purebred purple and the other purebred white then 100% of the offspring will be purple but will carry the gene for the white color. Mendel used pea plants in his experiments and this is how he found out how some genes were dominant over others.
The second type is Incomplete Dominance. This is when alleles aren't dominant over each other. For example Snapdragons. If one parent is purebred red and the other purebred white, the offspring will be pink. As if both colors blended together to form a new color.
The third type is Co-Dominance. This is when both traits are expressed. For example Lentils. If one parent is purebred spotted and the other purebred dotted, the offspring will be spotted AND dotted. As if they weren't able to decide which one should b dominant so both are equally expressed.
