Detailed explanation-2: -What percentage of chromosomes are handed down by a sperm cell? A)75%.

Detailed explanation-3: -Asexual Reproduction: One parent always passes on a duplicate of all of its genes to offspring. Rare mutations aside, offspring can only be genetically identical copies, or clones, of the parent.

Detailed explanation-4: -Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone, an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation.
