Answer:
The correct answer is B the extra chromosome has typically undergone significant rearrangements.
Explanation:
Trisomy is a type of aneuploidy which is characterized by the presence or occurance of an extra copy of a particular chromosome.As a result the chromosomes in which the trisomy is occurring contain 3 arms instead of 2. Trisomy occur due to non disjunction of a particular chromosome during meiosis.
As a result a second copy of chromosome is present inside the cell containing that abnormal chromosome.If the same thing occur in the cell of gamet undergoing fertilization then there is a high chance that the embryo will carry that extra chromosome.
In case of humans Trisomy result in the rearrangement extra chromosome which ultimately give rise to
1 Trisomy 18 occur due to extra copy of chromosome no 18
2 Trisomy 13 occur due to extra copy of chromosome no 13
3 Trsomy 21 occur due to extra copy of chromosome no 21 which is also called down syndrome.
Answer:
population mating structure and culture. hopefully I'm right.
The fever of unknown origin, or the FUO can be defined as the condition when the body temperature of a person is at 101 degree Fahrenheit for at least a period of the three weeks without any observable underlying cause. The most common causes of the FUO includes, infections (such as Lyme disease, tuberculosis), malignancy (such as leukemia), inflammation (such as inflammatory bowel disease), and alcohol or drug abuse.
<span>the one that is not a source of genetic variation is : D. Asexual reproduction
In asexual reproduction, there is no fertilization process between male and female gender. Which mean the offspring that came from asexual reproduction would be exactly the same as its parent, without any chance of genetic variation</span>
