mention three limitations of asexual reproduction
Answers
Answer:
a) Asexual reproduction doesn't allow any type of genetic variation. All of the organisms are genetically identical and therefore share the same weaknesses. If the stable environment changes, the consequences could be deadly to all of the individuals. In other words, less genetic diversity gives the offspring a lesser chance of survival if the environment changes.
b) Through sexual mode of reproduction. Combining variations from two or more individuals would create new combinations of variants. Each combination would be novel, since it would involve two different individuals. The sexual mode of reproduction incorporates such a process of combining DNA from two different individuals during reproduction.
Answer:
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
