Question

Two heterozygous tall pea plants with purple flowers are crossed. The probability that one of their offspring will have white flowers is $1/4$ . The probability that one of wear their offspring will be short is $1/4$ . What is the probability that one of their offspring will be short with white flowers?

• A. Zero
• B. $1/16$
• C. $1/8$
• D. $1/4$

Answer 1

The correct option is D $1/4$

When two heterozygous tall pea plants with purple flowers are crossed the probability that one of their offspring will be short with white flowers, will depend on the individual probabilities of the characters as in the monohybrid cross. This means that the probability that one of their offspring will have white flowers is 1/4 and the probability that one of wear their offspring will be short is 1/4 (in case of monohybrid cross). So the cumulative probability of having offspring with short height and white flowers is (1/4) X (1/4) = 1/16.

So the correct option is '1/16'.
