Non-Mendelian Genetics
Ever wonder why some traits don't follow simple dominant-recessive patterns? In incomplete dominance, neither trait dominates, causing them to blend together. For example, when a white snapdragon (ww) crosses with a red snapdragon (RR), you get pink flowers (Rw) - a perfect blend of both parents.
Codominance is different - both traits show up equally rather than blending. When a white chicken (ww) mates with a black chicken (BB), their offspring have speckled feathers (BW) showing both colors distinctly.
Many characteristics like height, skin color, and weight result from polygenic inheritance - multiple genes working together to create a range of possibilities. This explains why these traits have so much variation in human populations.
Try This! Look at your own traits like eye color, hair texture, or height. Can you identify which might follow non-Mendelian patterns of inheritance?
Finally, sex-linked inheritance refers to traits carried on the X chromosome. Conditions like colorblindness and hemophilia appear more frequently in males because they only have one X chromosome, while females have two and typically need two affected X chromosomes to show these conditions.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Non-Mendelian genetics explores inheritance patterns that don't follow Mendel's simple dominant-recessive rules. These patterns help explain why some traits appear blended or why certain conditions affect males more than females.
