What is the answer with explaining and what I put in the empty box

In the red box it would be ‘bb’ with the trait being ‘b’, this is because the chart above and across from the read box are both ‘b’ so it is bb. The genotype of the offspring is ‘bb’. The offspring in the blue box is the first option, because it has two of the genes.

Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.

Bb it’s the 2nd one on the bbottom
