Question

which process produces clones?
asexual reproduction
sexual reproduction
chromosome duplication
gamete formation

Explanation:

Asexual reproduction involves only one parent and produces offspring that are genetically identical to the parent, which are clones. Sexual reproduction involves two parents and genetic recombination, so offspring are not clones. Chromosome duplication is part of cell - division processes but doesn't directly produce clones on its own. Gamete formation is part of sexual reproduction and leads to genetic variation.

Answer:

A. asexual reproduction
