Questions covering the articles "King Tut's DNA" and "The Risksand Rewards of Royal Incest."? Questions 1- 11 come from "KingTut's DNA." Questions 12-15 come from "The Risks and Rewards ofRoyal Incests."
Ive got some of the answers i just want to make sure they areright and need help with the others.
Question 1:
Tutankhamun was _____ when he ascended the throne. I answerd9
the anwers for the question to choose from were: 7, 9, 19,25
Question 2:
Tutankhamun reigned for _____ years. I put 10
the answers provided to choose from were: 10, 15, 23, 47
QUESTION 3:
Why had Dr. Hawas resisted DNA anaylsis of royal mummies priorto this study?
He was afraid of envoking a curse by disturbing the mummies
The embalming process was believed to make it impossible tocollect DNA.
The possibility of obtaining workable DNA samples withoutcontamination was just too great to justify disturbing themummies.
The mummies would have to be completely destroyed to collect theDNA.
QUESTION 4:
Why did the scientists collect the samples from deep inside thebones of the mummies?
Bones are the only tissue that remained to sample.
To avoid contamination from the priests and archeologists thathad handled the mummies, as well as the researchers themselves
QUESTION 5:
The DNA was easily extracted from the samples collected from themummies. TRUE OR FALSE

DNA sequencing determined that ________ was Tutankhamun's fatherand __________ was his grandfather.
my answer for this is: KV55 mummy; Amenhotep III
the provided answers to choose from were: KV55 mummy; AmenhotepIII -----OR------Amenhotep III; KV55 mummy
QUESTION 8:
Through DNA analysis and a CT scan to determine tha age of theKV55 mummy, scientists determined that the identity of the mummywas __________. MY answer is: Smenkhkare

QUESTION 10:
Which physical defects did Tutankhamun suffer from that wouldhave resulted from the genetic closeness of his parents? I chooseall of the above.
The provided answers to choose from were: club foot, a toe wasmissing a bone and other bones missing from his foot were distroyedby necrosis (tissue death), partial cleft palate, all of theabove.

The two female fetuses found in his tomb.
Both A and B.
Neither, there is no evidence that they were related.
QUESTION 12:
While European royalty avoided sibling incest, they did marryclose cousins. TRUE OR FALSE
I choose TRUE
QUESTION 13:
Genetic overlap resulting in congenital defects is one possiblereason for the almost univerasal taboo against incest. What is thepercentage of genetic overlap between full siblings?
6.25%
12.5%
25% QUESTION 14: Royal incest has been documented in ancient Egypt, Inca Peru,the Hawaiians and Thailand. Despite the obvious drawbacks ofcondensing genetic lines, which answer was not a reason thatroyalty ignored the taboo and practiced brother/sister andcousin/cousin pairings Because they were royalty and they thought they were not subjectto the same biological laws as common people. Marrying family protects assets and concentrates power. Forges alliances between royal houses, while keeping power amongkin Royalty had the money to pay for medical care. QUESTION 15: Rulers did not always mate solely with siblings. Many kings andpharaohs had children with unrelated consorts and concubinesensuring healthy offspring in case none resulted from theirmarriages |
