answer with explanation
Dear Student,
TtYy x TtYy
For TtYy, gametes are: TY, Ty, ty and tY
For Ttyy, gametes are: Ty and ty
After crossing, the F1 generation is:
TtYy, ttYy, TtYy, TtYy, TTYy, TtYy, TTyy and TtYy
Now as per the question, we need to find the progeny that is both green and tall.
We know that green and tall both are dominant traits.
So, the genotype of progeny that fulfils the given condition are: TTYY, TtYy, TTYy and TtYY.
Out of 8 possible genotypes of progeny we find that 3 of them satisfy the criteria mentioned in the question.
Hence, the probability for finding tall and green progeny is 3/8
Ans. Option 1 is correct.
Regards
