Answer:
Second Punnett on the first attachment.
Explanation:
In a 4 x 4 Punnett there are a total of 4 squares. Twenty five percent (25%) of 4 is 1. This means that only 1 square out of the 4 should have the genotype that you are looking for.
Okay going at it in a biological sense. Because red eyes is dominant, we know that the allele should be represented by a capital R. It is X-linked, so it should be on the X. The problem is looking for the probability of a male offspring so the combination should be XY (this means the offspring is male, XX is for females).
So taking that all together, you're looking for the genotype combination:
So you need to find the Punnett that has only 1 square with this combination. The attachment shows which specific Punnett:
