Question

In a genetic experiment involving flower color in phlox, a ratio of 3 blue-flowered plants to 1 whiteflowered plant was expected. The observed results were 35 blue-flowered plants and 14 white-flowered plants. Does the observed ratio differe significantly from the expected ratio?

Answer 1

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

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.
