Bio class 25

Today in class we learned how to solve for the phenotypic and genotypic ratios using two different genes.

Example: 

Here you have to solve for the different genotypes before you can solve for the specific ratios. Another way to do it is to use the the regular punnet square and use the fractions to solve for the ratios.

Example:

Here you can multiply the different fractions and solve for either a genotypic ratio or a phenotypic ratio.
