Answer:
B) DNA could not be accurately replicated
Explanation:
Parkinson's disease is characterized by a deficiency in movement due to an anomaly in the nervous system of the body. However, according to this question, the cause of Parkinson's disease is unknown, although research points out that it may be due to defective nuclei in the cells of those affected.
Since Parkinson's disease is considered to be related to a defective nuclei at the cellular level, the most likely result is that DNA could not be accurately replicated. This is because DNA is located in the nucleus, and hence, a defective nucleus will affecti the DNA.
N.B: The other options are not related to the nucleus
Answer:
50% chance or 1/2.
Explanation:
Let's denote the no freckles allele with f and the freckles allele with F since it is dominant over the no freckles trait.
One parent is homozygous recessive: ff
The other parent is heterozygous (So they have freckles): Ff
Let's do a Punnett Square to calculate the possibility of the offspring having freckles or not. (The Punnett Square may not be perfect)
<u> | F f</u>
f | Ff ff
f | Ff ff
Two of the offspring have Ff, meaning they will have freckles, and two of the offspring have ff, meaning they will not have freckles.
2 out of 4 don't have freckles, which means a 50% chance or 1/2.
