Answer:
Hemophilia is a x-linked recessive inherited bleeding disorder. in this disease blood does not clot properly due to the decreased level of blood clotting factor VIII (8) or factor IX (9).
In x-linked recessive condition, the disease is transmitted from father (affected male) to his daughter and mother (affected female) to her son and skip of generation getting affected is also occurs.
- there will be 50% chance of her (S.R.) each son to be affected with hemophilia.
Explanation:
Hemophilia is caused due to mutation of one gene which is responsible for the making of proteins of blood coagulation factor viii or ix. the affected person bleeds continuously from any injury and that can cause serious issues.
here,
grandfather of s.r is affected (xₐy) and grandmother is normal (xx) will produce
↓
s.r's mother who is a carrier (xₐx) [as xₐy and xx will produce 100% carrier xₐx daughter]
↓
s.r's mother is a carrier (xₐx) but her father is normal (xy) will produce,
↓
s.r who has 50% chance of being carrier (xₐx) and 50% chance of being normal (xx) [as she is the only child] and she has a normal (xy) partner, they will give,
↓
- if s.r is a carrier (xₐx) then one of her son will be affected (xₐy) [as xₐx and xy =xₐy]
- if s.r is normal (xx) then her son will be normal (xy) [as xx and xy will give xy]
here,<u> 50% chance of her son to be affected with hemophilia</u> [as S.R of being affected is more considerable].
Answer:
The correct answer to the question: Which of the folowing structures would be considered an accessory organ to the digestive system and NOT part of the alimentary canal?, would be: A: Pancreas.
Explanation:
The accesory organs to the digestive systems are defined as organs that in some part play a role in the entire process of digestion of food, but are not directly a part of the digestive tract itself. As such, the pancreas, though resposible for secreting components that are essential to the process of absorption of nutrients, and management of them, is not part of the digestive system and fufills tasks outside of the purpose of the digestive system, which is, to manage the digestion, absorption and excretion of nutrients and foodstuffs.
