Final answer:
Option (B), The probability that one of the offspring would have 18 total toes is 50% (option B).
Step-by-step explanation:
The probability that one of the offspring would have 18 total toes can be calculated based on the genetics of the parents.
Assuming that Jake and Lucy each contribute equal genetic material to their offspring, and that the gene for total toes is a simple dominant/recessive trait, there is a 50% chance that one of their kittens mates with another cat that has 18 total toes.
Therefore, the probability that one of their offspring would have 18 total toes is 50% (option B).
