4. The flowers of 4 o’clock plants may be red, pink or white. Reds crossed to whites only produced pink offspring. When pink flowered plants were crossed with each other, they produced 113 red, 129 white, and 242 pink. It is hypothesized that these colors are controlled by a single gene pair of incompletely dominant alleles. Is this hypothesis acceptable on the basis of a Chi-square test? Show your solutions below.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
