Answer:
Derived traits shared among the species or other groups in a dataset are key to helping us build trees. As shown above, shared derived traits tend to form nested patterns that provide information about when branching events occurred in the evolution of the species.

The answer to ur question is A
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.
Recombinant DNA is a type of artificial DNA which have genes that are taken from different organisms. During this process, a gene is take from one organism and putting the gene into another organism. Basically, the technology follows cut and paste scheme to form the new brand of DNA.
So to conclude this the technology cuts part of the DNA out to create a new DNA so you are cutting and pasting new DNA which is incredible.
Hope this helped.
