This pedigree chart shows three generations. The individuals are numbered from left to right, starting at the top left of the chart. Squares represent males and circles represent females. If the symbol is gray, that individual exhibits the recessive trait. If the symbol is white, the individual exhibits the dominant trait. On the first row there are two couples mated together. The first couple is made up of individuals #1 (recessive) and #2 (dominant). They have four offspring on the second row that all exhibit dominant traits: #5 (dominant), #6 (dominant), #7 (dominant), and #8 (dominant). The second couple in Generation #1 is made up of individual #3 (dominant) and individual #4 (dominant). They have three offspring in Generation 2: #9 (dominant), #10 (recessive), and #11 (dominant). Individual #8 from the first family and individual #9 from the second family mated together and produced three offspring in Generation 3. These offspring are #12 (recessive), #13 (dominant), and #14 (recessive).

A. Individual #11 must be homozygous for the recessive trait.
B. Individuals #3 and #4 must be heterozygous for the trait.
C. Individual #2 must be heterozygous dominant for the trait.
D. Individual #9 must be homozygous dominant for the trait.

Two diseases resulting from hyperfunction of the pituitary gland are:
Snezhnost [94]
Gigantism and acromegaly are the two diseases resulting from hyper function of the pituitary gland. Gigantism and acromegaly are conditions that are nearly always due to a pituitary adenoma that is because of excessive secretion of a growth hormone called hypersomatotropism. <span>If GH hypersecretion begins in childhood, before closure of the epiphyses pituitary gigantism occurs. It is a rare condition where skeletal growth velocity and ultimate stature are increased, but little bony deformity occurs. However, soft-tissue swelling occurs, and the peripheral nerves are enlarged. Hypogonadotropic hypogonadism and deferred puberty is also normally present, resulting in a eunuchoid habitus. While Acromegaly occurs after the growth plate cartilage fuses in adulthood, it is the same disorder of IGF-I excess but in acromegaly, an unadorned disease that morbidity and mortality rates are high because its often diagnosed late, where the disease is associated with cardiovascular, cerebrovascular, and respiratory disorders and malignancies. </span>
