Question

Question 25 of 25 In the fruit fly, Drosophila melanogaster, a known deletion on the X chromosome removes both a gene involved in the fly's development and the gene for eye color. The deletion is lethal when homozygous or hemizygous. Flies that are heterozygous for the mutation are viable, but have indentations at the wing margin. Therefore, the deletion is named the Notch mutation. The allele for wild-type eyes is dominant over the allele for white eyes. Predict the phenotypic ratio of the offspring from a cross between a white-eyed notched female and a wild-type male. O 1 white-eyed female : 1 notched female : 1 white-eyed male O 1 white-eyed notched female : 1 wild-type female : 1 white-eyed notched male : 1 wild-type male O 1 wild-type female : 1 notched female : 1 white-eyed male : 1 white-eyed notched male O 1 wild-type female : 1 notched female : 1 white-eyed male O 1 wild-type female : 1 notched female : 1 white-eyed male : 1 white-eyed notched male

In the fruit fly, Drosophila melanogaster, a known deletion on the X chromosome removes both a gene involved in the fly's development and the gene for eye color. The deletion is lethal when homozygous or hemizygous. Flies that are heterozygous for the mutation are viable, but have indentations at the wing margin. Therefore, the deletion is named the Notch mutation. The allele for wild-type eyes is dominant over the allele for white eyes.

Predict the phenotypic ratio of the offspring from a cross between a white-eyed notched female and a wild-type male.
O 1 white-eyed female : 1 notched female : 1 white-eyed male
O 1 white-eyed notched female : 1 wild-type female : 1 white-eyed notched male : 1 wild-type male
O 1 wild-type female : 1 notched female : 1 white-eyed male : 1 white-eyed notched male
O 1 wild-type female : 1 notched female : 1 white-eyed male
O 1 wild-type female : 1 notched female : 1 white-eyed male : 1 white-eyed notched male
