Dominant alleles is the answer!
The answer is C. The first option is highly unlikely, the second option is impossible, and C is a much more likely answer than D.
The answer would be A: 1:16
This is because the letters mean:
Y: yellow
y: green
S: round
s: wrinkled
Thus, because the lowercase letters represent recessive alleles, both letters must be lowercase in order for the gene to show in the offspring.
So, if you wanted green, wrinkled, seeds, the only option (in letter form) would represented by:
ssyy
Therefore, because there is only one block with those letters, and sixteen blocks total, the ratio is 1:16.
