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.
Energy is ever-existing - energy does not disappear or is not created from nothing. Energy is only transferred from one system to another. Energy is only transformed from one type/form of energy to another type/form of energy. So, the energy of a system is either converted into another type of energy in that same system or is extinct to another system.
