ASEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which best describes one disadvantage of asexual reproduction?
A
It increases biodiversity
B
It decreases biodiversity
C
It decreases population size
D
It increases combination of traits
E
It produces diverse offspring
Explanation: 

Detailed explanation-1: -The major disadvantages of asexual reproduction are: Lack of diversity-Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent.

Detailed explanation-2: -Asexually reproducing organisms spend fewer resources for the same reproductive output, meaning their populations grow and expand faster than sexually reproducing ones. On the other hand, asexual populations have reduced genetic diversity and, hence, lower adaptability to changing environments.

Detailed explanation-3: -The disadvantage of asexual reproduction is that organisms do not receive a mix of traits from both parents. An organism that is born through asexual reproduction only has the DNA from the one parent. In fact, the offspring is genetically an exact copy of the parent.

Detailed explanation-4: -Stick insects that reproduce asexually cannot adapt as quickly in the course of evolution as sexually reproducing species, leading to a decrease in biological diversity, according to new research.
