Here's why:
* Genetic Diversity: Sexual reproduction involves the combination of genetic material from two parents (male and female). This creates offspring with unique combinations of genes, leading to genetic diversity within the species.
* Adaptation: Genetic diversity allows for better adaptation to changing environments. Offspring with advantageous traits are more likely to survive and reproduce, passing those traits on to the next generation.
* Mating Rituals: Deer engage in elaborate mating rituals, such as bucks competing for the attention of females, which are characteristic of sexual reproduction.
Asexual reproduction, on the other hand, involves only one parent and results in offspring that are genetically identical to the parent. While this can be beneficial in stable environments, it doesn't offer the advantages of genetic diversity that sexual reproduction provides.
