In Drosophila,an individual female fly was observed to be of the XXY chromosome complement normal autosomal complement and to have white eyes as contrasted with the normal red eye color of wild type.
-The female's mother and father had red eyes.The mother,however,was heterozygous for the gene for white eyes.Knowing that white eyes are X- linked and recessive,present an explanation for the genetic and chromosomal constitution of the XXY,white- eyed individual.
A) nondisjunction in meiosis I or II in father
B) nondisjunction in meiosis I of the mother
C) nondisjunction in meiosis II of the mother
D) nondisjunction in meiosis I of the father
E) nondisjunction in meiosis I of both the mother and father
