Answer:
Smooth & yellow: 9

Explanation:
Gene controlling seed color are yellow Vs green
Gene controlling seed texture are smooth Vs wrinkled
In F1 generation, A true breeding smooth green plant (SSyy) is crossed to a true breeding wrinkled yellow (ssYY)
Off spring in F1 generation are smooth yellow (SsYy)
This means smooth texture is dominant over wrinkled texture and yellow color is dominant over green
in F2 generation, the cross is carried between SsYy
SY Sy sY sy
SY SSYY SSYy SsYY SsYy
Sy SSYy SSyy SsYy Ssyy
sY SsYY SsYy ssYY ssYy
sy SsYy Ssyy ssYy ssyy
Smooth & yellow: 9
smooth & green: 3
wrinkled & yellow: 3
wrinkled & green: 1
