Page 2: Advanced Inheritance Patterns and Sex-Linked Traits
This page delves deeper into multiple alleles and introduces polygenic inheritance and sex-linked traits.
Example: Blood typing demonstrates both codominance and multiple alleles, with IA and IB being codominant, and i being recessive.
Definition: Polygenic inheritance occurs when traits are controlled by multiple genes, each contributing a small effect to the overall phenotype.
Example: Height, eye color, and skin color are examples of polygenic traits in humans.
Highlight: Sex-linked traits are controlled by genes located on sex chromosomes, primarily the X chromosome, affecting males and females differently.
Vocabulary: A carrier is an individual who carries a recessive allele but doesn't show the trait, common in X-linked inheritance.

Page 3: Pedigree Analysis
This page focuses on the practical application of genetic inheritance through pedigree analysis.
Definition: A pedigree is a chart that shows the inheritance of traits through multiple generations in a family tree format.
Highlight: Pedigrees are essential tools for tracking inheritance patterns and predicting genetic outcomes in families.
Example: Pedigrees can help visualize the inheritance of traits like hemophilia and color blindness across generations.

Page 1: Introduction to Non-Mendelian Inheritance Patterns
This page introduces fundamental concepts of non mendelian genetics, focusing on key inheritance patterns that differ from classical Mendelian genetics.
Definition: Codominance occurs when both alleles are fully expressed in the heterozygous condition, resulting in both traits being visible in the phenotype.
Example: In chickens, when black (FB) and white (FW) feather colors are inherited together, they produce a checkered pattern (FBFW) where both colors are distinctly visible.
Definition: Incomplete dominance is a condition where one allele is not completely dominant over another, resulting in a blended intermediate phenotype.
Highlight: Multiple alleles refer to genes that have more than two possible allelic forms, as seen in blood types (A, B, AB, O).

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.
