Asexual reproduction

The governing concept is asexual reproduction. It involves one parent, and the offspring receive a copied set of genetic material from that parent. Copying is generally accurate, although small differences can arise through copying errors or mutations. Since genetic material from two different parents does not combine, variation is usually much less than in sexual reproduction. Thus option A is correct; the other choices contradict the features of asexual reproduction.

The governing concept is asexual reproduction and genetic continuity. In asexual reproduction, one parent produces offspring without fusion of male and female gametes. Cell division generally copies the parent’s genetic material, so the offspring receive nearly the same genes and are often called clones. Small differences can still arise through mutations. Option A is correct; two-parent fusion describes sexual reproduction, and chromosomes are present in these cells.

Asexual reproduction usually involves one parent, so the offspring are genetically very similar to that parent. However, DNA copying is not perfectly error-free. A small copying error can create a mutation, and if it is retained in the offspring, it produces slight variation. Therefore option A is correct. Fusion of two parents describes sexual reproduction, while food changes do not directly rewrite inherited DNA.

Asexual reproduction usually produces genetically similar offspring because only one parent contributes genetic material. However, DNA copying is not perfectly error-free. Small copying errors, or mutations, may arise and can create a new inherited variation if they occur in reproductive cells or the organism’s reproductive lineage. Therefore C is correct. Food does not always alter genes, colour does not change automatically, and two-parent contribution describes sexual reproduction.
