Final answer:
The question likely contains a typo regarding offspring with 'only one eye'. Based on genetic inheritance principles, using a Punnett square, none of the offspring from the given cross would literally have 'only one eye'.
Step-by-step explanation:
The question regards genetics, more specifically Mendelian genetics, and it explores the inheritance patterns of eye color in fruit flies. When discussing how many offspring would have only one eye, it's expected that this was a typo since the question data provided talks about eye color, not the number of eyes. Therefore, we focus on the genetic outcome of eye color.
Punnett Square Results
First, to answer this question, we would use a Punnett square to predict the genotypes of offspring from a cross between a white-eyed male (hemizygous recessive) and a red-eyed female that is heterozygous for red eye color.
- A white-eyed male would have the genotype 'Xy'.
- A heterozygous red-eyed female would have the genotype 'XWXw'.
Predicted Offspring Ratios:
Crossing these two would yield the following ratios of offspring:
- 50% of the male offspring would have white eyes (hemizygous recessive).
- 50% of the male offspring would have red eyes (hemizygous dominant).
- 50% of the female offspring would have red eyes (heterozygous).
- 50% of the female offspring would have white eyes (homozygous recessive).
So, to directly answer the question, none of the offspring would have only one eye. If we're talking about having one type of eye color, then yes, certain percentages of offspring will have one type of eye color (either red or white based on the genetic cross).
