What is one aspect of sexual selection in the context of genetic disorders?

Selecting embryos to avoid sex-linked diseases is a key aspect of sexual selection in the context of genetic disorders. This practice involves the use of advanced reproductive technologies, such as preimplantation genetic diagnosis (PGD), to identify specific genetic conditions that can be passed down through genes linked to sex chromosomes, such as hemophilia or Duchenne muscular dystrophy. By selecting embryos that do not carry these harmful genetic traits, prospective parents can increase the likelihood of having healthy offspring and reduce the risk of serious health issues associated with sex-linked genetic disorders.

This focus on genetic health is an important evolution in reproductive choices, emphasizing the selective aspect of sexual reproduction where individuals aim to pass on favorable genetic traits to the next generation, thereby enhancing the overall fitness of the population.
