NEET BIOLOGY

Detailed explanation-1: -In asexual reproduction an exact genetic copy of the parent organism is produced (a clone ). Unlike sexual reproduction, asexual reproduction only introduces genetic variation into the population if a random mutation in the organism’s DNA is passed on to the offspring.

Detailed explanation-2: -Asexual reproduction involves a single parent and is hence not ideal for facilitating variations. Organisms raised are exact copies of their parents and are known as clones. Due to their identical set of chromosomes, they exhibit no or very little variations.

Detailed explanation-3: -We find that asexual individuals harbor many more DNA mutations than sexual individuals. Importantly, asexual genotypes are more likely to retain mutations in highly-conserved sites (shared across species) that cause protein changes.

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: -There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.
