Plz answer. 

A researcher has made a UAS transgenic line that drives a muscle transcription factor
that is attached to GFP (green florescent protein). This line is homozygous viable so
she keeps it as a pure line. She gets a fly line that has a promoter construct that
expresses Gal4 in the eyes, and that line is homozygous lethal, what a pain. So she
identifies a carrier for the Gal4 transgenic and crosses it to one of her UAS flies, and
looks at the progeny. Where does she expect to see GFP, and what are the numbers
she should expect? (Hint: use a Punnet square, and first figure out if your parents are
homozygous or not.)
No expression in this generation.
The eyes in one eighth of the progeny.
The eyes in one quarter of the progeny.
The eyes in one half of the progeny.
The eyes in all of the progeny.
