In the rare rainbow rose, it has been shown that flower color is controlled by 2 genes. No one knows how the 2 genes are related and several hypotheses have emerged to explain how they interact to produce flowers with purple, yellow, and green pedals. You cross purple and green flowering plants, and find that F1 are all yellow colored. You allow F1 to self-fertilize and this produces 222 purple, 222 yellow and 222 green flowers. The 2 most popular theories are: a co-dominance relationship or an epistatic relationship between the 2 genes. Your team deduces that if co-dominance should result in 216 purple, 220 yellow and 230 green. Where as, an epistatic relationship should result in 250 purple, 200 yellow, and 216 green   1-Calculate the chi-squared value for the co-dominance hypothesis? (Give your answers with 3-decimal places e.g. 45.022)

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
