Behavioral Neuroscience 4.1 Stop And Check

Accounting4 CardsCreated 10 days ago

This deck covers key questions and answers related to genetic sensitivity to taste and the differences between sex-linked and sex-limited genes.

Suppose you have high sensitivity to the taste of PTV. If your mother has low sensitivity, what (if anything) can you predict about your father’s taste sensitivity?

If your mother has low sensitivity, you must have inherited your high sensitivity gene from your father, so he must have high sensitivity

Suppose you have high sensitivity to the taste of PTV. If your mother has low sensitivity, what (if anything) can you predict about your father’s taste sensitivity?
If your mother has low sensitivity, you must have inherited your high sensitivity gene from your father, so he must have high sensitivity
Suppose you have high sensitivity to tasting PTC. If your mother can also taste it easily, what (if anything) can you predict about your father’s ability to taste it?
If your mother has high sensitivity to the taste of PTC, we can make no predictions about your father. You may have inherited a high-sensitivity gene ...
How does a sex-linked gene differ from a sex-limited gene?
A sex linked gene is on the X or Y chromosome. A sex limited gene is on an autosomal chromosome, but activated in one sex more than in the other.
Suppose someone identified a “gene for” certain aspects of sexual development. In what ways might that statement be misleading?
Almost any characteristic depends on more than one gene, as well as influences from the environment.

If your mother has high sensitivity to the taste of PTC, we can make no predictions about your father. You may have inherited a high-sensitivity gene from your mother, and because the gene is dominant, you need only one copy of the gene to taste PTC
