Detailed explanation-1: -The correct option is C. All of the genetic information comes from one parent. Explanation: Astrammina rara is a unicellular organism that reproduces by the asexual method of reproduction.
Detailed explanation-2: -Asexual reproduction is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it is reproduction which almost never involves ploidy or reduction. The offspring will be exact genetic copies of the parent, except in the specific case of automixis.
Detailed explanation-3: -Asexual reproduction does not involve the formation and fusion of the gametes. Hence, fertilisation does not takes place. Vegetative propagation, a type of asexual reproduction involves the development of new individuals from the vegetative parts (root, stem and leaf) of the plant.
Detailed explanation-4: -Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.
Detailed explanation-5: -Budding. In budding, organisms reproduce by having new individuals split off from existing ones, which results in genetically identical parent and daughter organisms.
