Fun with Punnett squares

In this video I go over three different possible situations that you can have when making a Punnett square. I show you how to set up the Punnett Square, do the cross and then figure out the genotypic and phenotypic ratios.

what does it mean whe nit says phenotypes for the parents

[RachelKPG]

@royodrummer This would be the physical description of the parents traits

[RachelKPG]

Traditionally you put the mother on the side and the father on the top, but you will get the same answer either way.

What I don't understand is how can someone have blue eyes & brown eyes at the exact same time? Because Bb would be BrownBlue

[RachelKPG]

Brown eyes are dominant to blue eyes, so that is the trait that is shown
