why is sexual reproduction better than a sexual reproduction for ensuring the survival of a species in a changing environment?
Asexual reproduction has less genetic variety. Any catastrophic environmental change would effect all organisms. Since sexual reproduction gives a variety of genetic combinations, some organisms would probably survive.
Why does this Gotta be so oooooooooooooooo hard!!!!!
Sexual reproduction is generally considered better than asexual reproduction for ensuring the survival of a species in a changing environment due to its advantages:
1. Genetic Variation: Sexual reproduction involves the combination of genetic material from two parents, leading to offspring with varied genetic characteristics. This genetic diversity provides a wider range of traits, which increases the chances of some individuals being better adapted to changes in the environment. This adaptability increases the overall survival rate of the species in a changing environment.
2. Ability to Evolve: The genetic variation resulting from sexual reproduction allows for easier adaptation and evolution. Environmental changes, such as the emergence of new predators, diseases, or different climatic conditions, require species to adapt in order to survive. Sexual reproduction promotes the mixing and recombination of genes, providing a platform for beneficial genetic variations to arise and for species to evolve and adapt to new challenges.
3. Increased Resistance to Diseases: Sexual reproduction can contribute to increased resistance to diseases and parasites. The recombination of genetic material in sexual reproduction can lead to offspring with diverse immune system responses, making it more difficult for diseases to overcome the defenses of the entire population. This enhances the chances of survival for the species in a changing disease landscape.
4. Removes Harmful Mutations: Sexual reproduction aids in eliminating harmful genetic mutations from the population. Harmful mutations can occur spontaneously, but the mixing of genes can help "dilute" these mutations over generations. With asexual reproduction, harmful mutations can accumulate and persist in the population, potentially hindering the species' ability to adapt and survive.
To summarize, sexual reproduction is advantageous in changing environments because it promotes genetic diversity, facilitates the evolution of new traits, enhances resistance to diseases, and helps remove harmful mutations from the population. These factors collectively increase the chances of species survival and adaptation.
