#AP Biology: Non-Mendelian Genetics - Your Ultimate Study Guide 🧬

Hey there, future AP Bio master! Let's dive into the fascinating world of non-Mendelian genetics. This is where things get a little more complex than simple dominant and recessive traits, but don't worry, we'll break it down together! This guide is designed to be your go-to resource the night before the exam. Let's make sure you're feeling confident and ready to ace it!

#Introduction to Non-Mendelian Genetics

Most traits don't follow simple Mendelian inheritance patterns. Instead, we see a variety of non-Mendelian patterns. Key examples include multiple alleles, sex-linked traits, incomplete dominance, and codominance. Let's explore each one:

#Multiple Alleles

Key Concept

Instead of just two alleles (dominant and recessive), some genes have multiple alleles. This means there are more than two versions of a gene that can contribute to the phenotype. Think of it like having a wider range of options for a particular trait.

#Human Blood Types

A classic example of multiple alleles is human blood type. The ABO blood group system has three alleles: I^A, I^B, and i. I^A and I^B are codominant, while i is recessive.

#Rabbit Fur Color

Another great example is fur color in rabbits. There's a dominant C allele and three different recessive c alleles, leading to four different phenotypes.
