Suppose your mentor wanted to create a hybrid sea urchin species to study whether acutely introducing large-scale genetic diversity increases life span.

Suppose your mentor wanted to create a hybrid sea urchin species to study whether acutely introducing large-scale genetic diversity increases life span. To make the hybrid species, she decided to mix sperm from Arbacia luxila and eggs from Lytechinus variegatus in a very small petri dish in an in vitro fertilization assay with hopes to raise the progeny from this process. Since you’re taking Developmental Biology, you know this will never work! Why won’t this work? What could you suggest to improve on her assay to make the in vitrofertilization assay work?
