Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Asexual reproduction results in identical offspring unless which of the following occurs?
A
Natural selection
B
Cloning
C
Crossing over
D
Mutation
Explanation: 

Detailed explanation-1: -This process is called asexual reproduction. The new cells produced by asexual reproduction are genetically identical to the original parent cell unless some mutation occurs.

Detailed explanation-2: -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-3: -Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring. Sexual and asexual reproduction have advantages and disadvantages-which is why some organisms do both!

Detailed explanation-4: -Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.

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.
