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. All the negative mutations persist for generations.
Detailed explanation-2: -Offsprings are identical to the parent genetically and morphologically. They are the exact copy or clone of the parent. There is no recombination of genetic material takes place in asexual reproduction. Hence, there is no variation or genetic variability seen in the individual produced by asexual reproduction.
Detailed explanation-3: -With asexual reproduction you get two times as many offspring and two times as many genes into the population."
Detailed explanation-4: -Sexual reproduction results in genetic variation, or genetic differences, between parents and offspring. Offspring inherit one set of chromosomes from each parent. So, an offspring has a mixture of chromosomes (and alleles) from its two parents.
Detailed explanation-5: -The biggest disadvantage of asexual reproduction is that, by nature, it produces offspring with the same genes and traits as the parent plant. Because offspring are genetically identical, asexual reproduction is a disadvantage when a species needs to adapt to changing environments.
