Final answer:
Polyploid crops tend to produce larger fruits and enhanced traits due to having more than two sets of chromosomes. The correct answer is option c).
Step-by-step explanation:
In agriculture, polyploid crops like coffee, strawberries, or bananas tend to produce larger fruits and enhanced traits. Polyploidy, the condition of having more than two sets of chromosomes, is a common phenomenon in plant species and is often associated with increased size and improved characteristics in cultivated crops.
Agricultural crops like wheat, cotton, and bananas exhibit allopolyploidy, a form of polyploidy from hybridization between different species. This adaptation can lead to sterile plants that are propogated through cloning, which is advantageous when seedless fruits are desired, such as with many types of commercial bananas.
These crop forms can contribute to reduced genetic variability within a species due to their reproduction methods, but they also allow for the combining of favorable traits developed in parental lines. Monocultures of polyploid plants may, however, be susceptible to the same diseases due to homogeneity.
