Which of the following is a major disadvantage of asexual reproduction in organisms?
A
Increased energy expenditure during reproduction
B
Slower population growth compared to sexual reproduction
C
Requires two parents for reproduction
D
Lack of genetic variation among offspring
Verified step by step guidance1
Understand the concept of asexual reproduction: Asexual reproduction is a mode of reproduction where offspring are produced by a single parent without the involvement of gametes (sperm and egg). Examples include binary fission in bacteria, budding in yeast, and vegetative propagation in plants.
Recognize the advantages of asexual reproduction: It allows for rapid population growth, requires less energy compared to sexual reproduction, and does not require finding a mate, making it efficient in stable environments.
Identify the major disadvantage: Asexual reproduction produces offspring that are genetically identical to the parent (clones). This lack of genetic variation means that if the environment changes or a disease arises, the entire population may be at risk because they all share the same vulnerabilities.
Compare with sexual reproduction: Sexual reproduction involves the combination of genetic material from two parents, leading to genetic variation among offspring. This variation increases the chances of survival in changing environments.
Conclude that the correct answer is 'Lack of genetic variation among offspring,' as this is the primary disadvantage of asexual reproduction, making populations less adaptable to environmental changes or threats.
