Explain how corn can be used as an example of Mendel's law of independent assortment.

Answer:

Corn acts as an example of Mendel’s law of independent assortment because each kernel on an ear of corn is an individual offspring resulting from a unique fertilization event. Traits such as kernel color and texture are controlled by different genes that assort independently during the formation of gametes. Consequently, each kernel inherits traits independently, receiving one allele for each characteristic from each parent. This leads to the variety of color and texture combinations seen across the kernels on a single cob.
