The correct answer is: A. A change in a cell's genetic material.

Mutations occur in DNA as a result of mistakes during the DNA replication (when repair mechanisms don’t fix it) or as the result of environmental factors (e.g. UV light). Mutations can have positive impact, by increasing the genetic variation or can have negative effect, causing the diseases or cancer.

In a two-factor cross, genes that are close together on the same chromosome follow mendel's law of independent assortment.
torisob [31]

False, it violates Mendel's law of independent assortment.

About mendel's law of independent assortment:

According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes. In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.

During his research on the genetics of pea plants in 1865, Gregor Mendel made the first observation of an independent assortment of genes and their related phenotypes. Mendel was doing dihybrid crosses, which are unions of organisms with two different features. He found that the trait combinations in his hybrids' offspring did not always correspond to the trait combinations in the parental organisms.
