Multiple alleles play a big role in how traits are passed down from parents to kids. They let a single trait have more than two different forms. This creates a wide variety of appearances, known as phenotypes.
Here’s an example:
Because of these alleles, we have four different blood types: A, B, AB, and O.
Now, let’s talk about genotypic ratios.
These ratios are what we expect to see when we do a genetic cross with two traits. They can result in all sorts of different combinations, which increases the genetic diversity in a population.
This can become complex.
For example, simple patterns that Gregor Mendel studied, like or , might not work in cases like polygenic inheritance. This type of inheritance shows traits that can change continuously, like the height of humans.
