Answer:
<u>Nervous System</u> could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson .
Explanation:
<u>PASRKINSON DISEASE -:</u> Parkinson's disease is a progressive nervous system condition. Several regions of the brain are affected by the condition, especially an area called substantia nigra that regulates balance and movement.
A trembling or shaking (tremor) of the limb is often the first sign of Parkinson's disease, particularly when the body is at rest. Typically, on one side of the body, the tremor starts, usually in one hand. The head, legs , feet, and face can also be affected by tremors. Other hallmark symptoms of Parkinson's disease are rigidity or rigidity of the limbs and body, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability).
Emotions and thinking ability (cognition) can also affect Parkinson's disease. Psychiatric disorders such as depression and visual hallucinations are created by some affected persons. There is also an increased risk of developing dementia in people with Parkinson's disease, which is a loss in intellectual functions, including judgment and memory.
Hence , the answer is <u>the nervous system and other regions of brain</u> where the disease has a direct result of having a defective nuclei and may shed light on the cause of Parkinson .
Answer:
The phenotypes are as follows
Purple, full- 9
Purple, constricted- 3
White, full- 3
White, constricted- 1
Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.
Explanation:
This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).
In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1
Purple color, full pod- 9
Purple color, constricted pod- 3
White flower, full pod- 3
White flower, constricted pod- 1
