A. Both red eyed
B. Both white eyed
C. Red eyed daughter and white eyed son
D. Red eyed son and white eyed daughter
This question was posed to me at a job interview.
I need to ask this question from Chromosomal Theory of Inheritance topic in chapter Chromosomal Basis of Inheritance of Cytogenetics
Explanation: The eye colour of Drosophila is an X linked gene. So as the female is homozygous recessive white and the male has on red allele and one Y chromosome, sons will only get Y chromosomes from father. Sons will thus be white eyed while daughters will be red eyed.
