Mendel studied pea plants for particular traits. When observing the results of his experiments, he created two laws of inheritance. How is a scientific law formed?
A scientific law is formed when repeated observations and experiments consistently support a pattern or relationship in nature.
The law of states that traits are passed from parents to offspring independently of one another.
independent assortment
The law of explains how alleles separate during gamete formation.
segregation
Explain how corn can be used as an example of Mendel's law of independent assortment.
Corn demonstrates independent assortment because each kernel receives one allele for color and one allele for texture from each parent, and the traits are inherited independently. This produces different combinations of kernel color and texture, so one cob can contain kernels with multiple colors.

Explain how the alleles were passed from parents to offspring.
The Gg parent passed a G allele, and the gg parent passed a g allele. The offspring received Gg, so they had green pods.
