In Drosophila, an X-linked recessive allele produces yellow body color. The cross of a yellow female and a male with wild-type body color usually produces wild-type females and yellow males. Occasionally however, a yellow female is produced. Explain how the unusual female is produced.

It happens when non-disjunction in the female parent produces an egg with two X chromosomes. The XXY zygote will develop as female and will be homozygous for the recessive yellow-body allele.
