Asexual reproduction

In Class 10 Science, the topic of asexual reproduction explains how a single parent produces new organisms without the fusion of gametes or fertilisation. As part of the chapter “How do Organisms Reproduce?”, students learn the main methods, including binary fission, budding, fragmentation, regeneration, spore formation and vegetative propagation in plants. They also understand why the offspring are usually genetically similar to the parent and how asexual reproduction supports rapid multiplication in suitable conditions.

01Why is variation comparatively less in asexual reproduction?

0 reads0 helpful★ – (0)

Answer and explanation

Correct answer: A. Because genetic material is copied from only one parent

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.

02Why are offspring in asexual reproduction very similar to the parent?

0 reads0 helpful★ – (0)

Answer and explanation

Correct answer: A. Because genetic information comes from only one parent

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.
