Incomplete dominance

In in complete dominance, there is no recessive trait. Both traits are expressed
in the offspring. For example, if a red (R) flower was pollinated by a white (W)
flower, the flowers that would sprout from the seeds would be pink (RW).

Co-dominance

Co-dominace is very similar to incomplete dominace. The difference is that instead of merging the traits together to get something new, both traits are visible. For example, if a white (W) chicken and a black (B) chicken had an offspring, it would be white and black (BW)
Multiple Alleles

There are some occasions where more than two alleles are needed. One example is blood cells.
I"A", I"B", and "i" are the three alleles. I"A" and I"B" are dominant while "i" is reccesive.

pOLYGENIC INHERITANCE
inheritable character that is controlled by several genes at
once. Examples of polygenic inheritance in humans include hair, eye, skin color,
and intelligence. Some disorders caused by polygenic traits are autism and
diabetes.

Sex Linked
Sex linked traits are traits that may differ in the offspring depending on if the offspring is male or female.
