How does this diagram represent Gregor Mendals experimental work with peas?

What precisely did Mendel do?

How do you make reciprocal crosses?

Why do you make reciprocal crosses?

Mendel then allowed the progeny (F1 - hybrids) to self pollinate and analyzed the resulting progeny F2.

Mendel analyzed
seven different factors pea (Pisum sativum L.)s

 Mendel's seven
F 2 populations     

 Mendels
five points.

  Back Cross = Take the F1 and cross it with either parent. What would you expect if you back crossed to the dominant or yellow parent.
 

Test Cross = Take the F1 hybrid or any organism suspected of being a hybrid and cross it to an organism that is homozygous recessive for the trait or traits involved.

Note: This is similar to a back cross to the recessive parent.

Do Mendel's Laws work in corn [Zea mays]?
