Your friend will talk about the definition of evolutionary medicine, and there by understanding the health and diseases
Explanation:
- Evolutionary medicine is the understanding the health and diseases using the evolutionary theory
- Evolutionary theory gives an idea of the heritable and morphological changes in the organism. 
- Today, the field of research on evolutionary medicine is advanced to the molecular and psychological mechanism of health and diseases. 
- Hence, your friend will talk about the evolutionary understanding of the health and diseases from the lens of the evolution of species. To create an understanding of the evolutionary medicines there need to ab understanding of the heath and diseases of previous ages.

Answer: D. It yields chromosomes that contain both maternal and paternal DNA.
Explanation:
The recombination or crossing over is a genetic process. It takes place during the Prophase I of meiosis. The homologous pair align and held together by synapsis. This results in the mixture of genes combination formed from both parents that can be represented as a single chromosome. 
If the recombination do not occur then each chromosome will be either 100% maternal or paternal. Thus recombination assures the recombinant chromosomes which consists of genetic material from both parents. Thus the genetic diversity of offspring increases.
