Please help me. I dont understand how to do this. Can you pls tell me what to put in the box​

The genotypes go in the boxes to the upside and left of the four boxes and then find the possible genotypes of the offspring by filling in the punnet square. So for one of them two of the genotypes on the outside of the punnet square could be XbXb and XbY and because the Xb is in front of the Y the Xb is dominant and Y is recessive. So the for one punnent square the answer would be XbXb and XbY = XbXb. and the XbXb and XbY go outside the punnet square and the XbXb that is from the XbXb and XbY goes in the four boxes of the punnet square.

Explanation: Steps to solve a Punnet Square:

"1. determine the genotypes of the parent organisms

2. write down your "cross" (mating)

3. draw a p-square

4. "split" the letters of the genotype for each parent & put them "outside" the p-square

5. determine the possible genotypes of the offspring by filling in the p-square

6. summarize results (genotypes & phenotypes of offspring)"(k12)
