I'm definitely not an expert at any means...but I may know the answer.

white eyes in fruit flies are recessive, the only way an offspring can result in white eyes, is if the parent is a carrier for white eye color. A homozygous white eyed fly and a heterozygous red/black fruit fly will have 3/4 red/black eyed offspring and 1/4 white eyed offspring.

If this is not right I'm truly sorry and hopefully someone else can help you out :)
