So what that means is this information is consistent with this square right over here because we are given a male that is fully colorblind. So we have x lowercase by and that is consistent with this punitive square. That tells us 100% of the males produced from that mating process will basically be color blindly. Now what this row tells us is 100% of our females will be the carrier for this particular trait. So they will have normal phenotype, but they will be half colored, they will be heterozygous as is given to us by this particular pedigree. So this pedigree information is consistent with the fact that it's sex link recessive.
