What discoveries in genetics have led to the realization that genetic mapping is not quite as simple as genes being linked or not? List two in your answer & explain how they added layers to our current understanding of mapping & gene expression. An example is epigenetics, the field of genetics that tracks expression based on environmental factors. Someone might carry two closely associated (“linked”) genes, but one’s expression is modified by environmental factors, making interpretation of whether they (genes) behave according to Mendelian principles difficult. Provide two more examples & list why you think they have made studying gene linkage somewhat tricky.
As a bonus list a fun fact about anything listed above.
2.)IMMUNOLOGY –
In 137 words or more using 2 references, please respond to the following question:
Why does the body have multiple methods to restrain immune response? (What could possibly go wrong?) The list of autoimmune disorders is constantly growing. Thinking about this from an evolutionary perspective, what advantage does having multiple means to restrain the immune response confer? In other words, why have backups (& backups of backups, etc.)?
