    Statement E and F are true because it states that: E. All F1 females are expected to be wild type- since the male parent is wildtype and the mutations are X-linked recessive (given) all the female progeny must be wildtype. F. F1 wildtype males appeared due to crossing over. This is possible when there occurs a crossing over within the XX female chromosome. Option 1 seems to be the best option because only in this option both statements E and F fall together along.
