An analysis of the susceptibility to major depressive disorder in monozygotic twins separated at birth revealed that the broad-sense heritability of this trait is 0.10 and its total phenotypic variance is 0.25
What is the variance of the genotypic value of this disorder? Show your work.
What will be an ideal response?
ANS:
H2 = VG/(VG+VE) and VP = VG+VE
Therefore:
H2 = VG/VP
VP *H2 = VG
0.1 *0.25 = 0.025
VG = 0.025

Susan ran a beef slaughterhouse. At the end of a very long day in which many cattle were processed, she found that there were several pounds of thyroid gland, unsalable as such. Therefore, she ordered the glands be ground into hamburger meat. If someone
were to buy, cook, and eat all of that thyroid-burger, what serious outcome would you predict for that customer? What will be an ideal response?
