Question
Chapter 16, Problem 5TYU
Summary Introduction
Introduction: DNA is the blueprint of life, which consists of genetic instructions in a cell. Any variations in the DNA may lead to genetic disorders or inherited diseases, as they are passed onto the next generation.

Suppose you are analyzing the DNA from the polar bodies formed during human oogenesis. If the woman who produced the oocyte has a mutation in a known disease gene, would analyzing the polar body DNA allow you to infer whether the mutation is present in the mature oocyte? Explain.
Identical twins each carry the same genome, but over time, can develop different phenotypes. How can you explain this?
