In a genetic experiment involving flower color in phlox, a ratio of 3 blue-flowered plants to 1 whiteflowered plant was expected
aliya0001 [1]

Answer: The observed ratio is different from the expected ratio.

Step-by-step explanation:

Since we have given that

Expected ratio :

Ratio of blue flowered plants to white flowered plant = 3:1

Observed results:

Number of blue flowered plants = 35

Number of white flowered plants = 14

So, Ratio of blue flowered plants : white flowered plants

35:14\\\\=5:2

So, 5:2 ≠ 3:1

Hence, the observed ratio is different from the expected ratio.
