The type of inheritance when both traits are mixed together
What is Incomplete Dominance
Changes that happen by nature over time caused by several different mechanisms
What is Natural Selection

A cross between purebred inflated pods is crossed with purebred for pinched pods. All of the offspring end up with inflated pods. Which trait is recessive?
Pinched pods
the type of dominance when only one gene is used and only has two possible alleles
What is Complete Dominance/Mendelian Inheritance?
Two or more genes interact to produce a single trait
What is Polygenic Inheritance

What is RR, Rr, and rr
If a purebred (homozygous) plant with green pods (dominant) was crossed with a purebred (homozygous) for yellow pods (recessive), what would all of the offspring be?
What is 100% heterozygous green pods
When both alleles are expressed equally at the same time
What is Codominance
A gene that has two more more possible alleles
What is Multiple alleles
