Dogs are inbred for such desirable characteristics as blue eye color, but an unfortunate by-product of such inbreeding can be th
Agata [3.3K]

Answer:

<h2>Option 2 is the right answer.</h2>

Step-by-step explanation:

We need to check if the two characteristics, <u>having blue eyes and being deaf are independent of each other or not</u>.

The above two characteristics will be independent if [Probability of being deaf with blue eyes] = {Probability of being deaf } {Probability of having blue eyes}

Now, the probability of having blue eyes is \frac{31}{100}.

The probability that the Dalmatians will be deaf is \frac{38}{100}.

The probability of being deaf with blue eyes is \frac{31}{100} \times\frac{42}{100}.

Since, 38 is not equals to 42, the two characteristics are not independent.
