Answer: Tau
Explanation:
NFTs or neurofibrillary tangles are insoluble twisted fibers. The tangles are abnormal accumulation that collect inside neurons. Their presence is also found in other diseases such as tauopathies. Statins have been shown to reduce neurofibrillary tangles in mouse models. Lithium has been shown to decrease the phosphorylation of tau. The tau protein is primary maker Alzheimer's disease.

Explanation:
Apomictic refers to plants and it means the offspring is genetically identical to the parent. Automictic means that gametes fuse after meiosis - which means offspring are genetically not identical to parents.
The disorder where the grandfather and the grandchild are affected is related with the X chromosome and is called Sex linked or X linked disorder.
<h3><u>Explanation:</u></h3>
All the sex linked disorders are recessive in character i.e the normal allele is dominant over the mutated allele. In females, there are 2 X chromosomes, so the mutated allele is only expressed when there are both the mutated alleles, else its masked by the dominant normal allele. But in males, there's only one X chromosome, so if a mutated allele is present, it's readily expressed.
If the Grandfather is diseased, then he must have that mutated allele in X chromosome. Through reproduction, its received by the mother, but she is normal because the other allele received from grandmother was normal. But mother has one of the X chromosomes with mutated allele, which is received by the grandson who again becomes diseased.
So the disorder must be X linked disorder
