Jane, a 48 year old woman with no history of health complications had recently noticed that her show and glove sizes had increased and that her rings no longer fit her fingers. As much as she wanted to attribute this to her recent weight gain her lower jaw was protruding and she noticed that her facial features were getting abnormally coarse. To make matters worse she was urinating much more frequently and feeling thirsty. An initial blood test revealed that her blood glucose level was above normal but that her insulin blood level was within normal range.
A) Given the information, explain the reason for elevated glucose levels and polyuria despite normal insulin levels.
B) How ware Jane's recent physical changes connected to her elevated glucose levels? Provide the underlying mechanism.

Anthropology:
1) If two parents are each carrying one copy of the allele for yellow eyes (Y) and for blue eyes (y), what are ALL the possible phenotypes of their children? (Assume that eye color is a simple, mendelian trait).
a) Yellow Only
b) Green Only
c) yellow and blue only
d) Yy
e) YY, Yy, yy
I picked yellow only but I guess I got that wrong
2) If a child is heterozygous for a particular trait, and the mother of that child is homozygous dominant for that trait, then the father would be… (There may be more than one correct answer - please select ALL possible answers).
Hint: it may be helpful to draw out some punnett squares.
A) Homozygous dominant
B) Homozygous recessive
C) Heterozygous
this one I picked A and B but that was wrong as well I thought the father would be A and B
