Answer:
The punnet square
Step-by-step explanation:
In order to create a punnet square you have to name the or put a representation to the genes, les say it would be C and N, C for colorblind and N for normal:
Father Mother
N N
C CN CN
N NN NN
So that would be the punnet square, remember that sex comes into consideration because women canĀ“t be colorblind nor carriers of the gene.
