B) by means of pleiotropy
C) through gene flow
D) all of the above

Nonadaptive traits can exist due to a variety of reasons. They might be linked to adaptive genes on the same chromosome, making them difficult to eliminate through natural selection. Pleiotropy, where a single gene affects multiple traits, can also result in nonadaptive traits if the gene has at least one beneficial effect. Additionally, gene flow, the transfer of genes from one population to another, can introduce nonadaptive traits into a population.
