The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. The advantages of asexual reproduction include:. In sexual populations, the males are not producing the offspring themselves.
This method of reproduction is advantageous when the environment is changing because the variation introduced leads to an increase in the probability that a variant that can deal with the change. These methods of asexual reproduction do not require another organism of the opposite sex.
But why, even in the face of fairly stable conditions, does sexual reproduction persist when it is more difficult and costly for individual organisms? Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation.
The genetic information from each individual combine to improve the foundation of the offspring, creating an adaptive way to begin managing the challenges of new environments. Fewer offspring are typically produced. Without outside intervention, many asexual organisms would either need to adapt over time to increase genetic diversity or their population numbers would be extremely limited.
In humans, practicing sexual reproduction is directly linked to better health. Individuals who show characteristics of both genders or no gender may not have the capability of participating in this part of the reproductive process. Syngamy is the permanent fusion of two haploid gametes to create a zygote.
The problem with STIs is that many of them have zero symptoms. Because the offspring of an asexual organism is essentially a clone of the parent, any negative mutations that are within the genetics of the organism will be passed down to the offspring.
Not only that, it only takes a single parent to produce such an offspring.

Asexual organisms are highly adaptive. Genetic diversity can be created, but the process is uncertain and somewhat unpredictable.
If the parent organism is successfully occupying a habitat, offspring with the same traits would be similarly successful. The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell.
Coprinus cinereus also produces spores by asexual reproduction.
