A trait in garden peas involves the curling of leaves. A two-factorcross was made by crossing a plant with yellow pods and curlingleaves to a wild-type plant with green pods and normal leaves. AllF1 offspring had green pods and normal leaves. The F1 plants werethen crossed to plants with yellow pods and curling leaves. Thefollowing results were obtained: 117 green pods, normal leaves115 yellow pods, curling leaves78 green pods, curling leaves80 yellow pods, normal leavesA. Conduct a chi square analysis to determine if these two genesare linked.B. If they are linked, calculate the map distance between the twogenes. How accurate do you think this calculated distance is?

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.
