Question
Determine the one and only one correct statement.
A. Flowers on Peak 1 are more phenotypically related to flowers on Peak 2 than they are to flowers on Peak 3.
B. Flowers on Peak 2 and Peak 3 differ by three phenotypes.
C. The most recent common ancestor of flowers on Peak 4 and Peak 2 have yellow anthers.
D. From an evolutionary standpoint, the Peak on which flowers first arose is Peak 1.
E. There are more phenotypic differences for the flower peak pair (Peak 4, Peak 2) than there are for the pair (Peak 4, Peak 3).

Correct statement is D - From an evolutionary standpoint, the peak on which flowers first arose is peak 1.
A is wrong because - peak 2 and peak 3 both have 4 phenotypes different from peak 1. so peak 1 is different in 4 phenotypes to both 2 and 3. so statement A is wrong.
B is wrong because - flower on peak 2 and 3 differ in 2 characters.
characters on peak 2 flowers are- spur colour ,petal colour, anther, spur length
Characters on peak 3 flowers are- spur colour ,petal colour, anther, petal tips
spur length and petaltips are 2 different characters among them.
C is wrong because- most comman recent ancestor of peak 2 and peak 4 is peak 1 flower who dont have yellow anthers.
E iswrong because phenotypic differences between flower peak pair 2 & 4 is 2 characters and 4 & 3 also have difference of 2characters.
characters of peak 4 flower- petal colour, spur colour
characters of peak 2 flower- petal colour, spur colour, anther, spur length
characters of peak 3 flower- petal color, spur color, anther, petal tips.
Hence option D is correct as we can see in diagram. Flower from peak 1 arise first.
