Question

Approximately 75% have a "__________," on the long arm of the paternally inherited chromosome 15

(organizer: Think "P" for Prader-Willi = Paternal)

Answer 1

Approximately 75% of individuals with the paternally inherited chromosome 15 have a deletion, which is associated with Prader-Willi syndrome, a genetic disorder characterized by persistent feelings of intense hunger and reduced metabolism.

Step-by-step explanation:

Approximately 75% have a "deletion," on the long arm of the paternally inherited chromosome 15. This deletion refers to a loss of function of specific genes on chromosome 15 and is associated with Prader-Willi syndrome. Prader-Willi syndrome is a genetic disorder that results in persistent feelings of intense hunger and reduced metabolism, leading to obesity and other cognitive and emotional problems.
