FALSE

Dementia can be described as a collective term for a number of diseases in which a person loses his/her memory, is unable to perform everyday tasks etc. Problems with short term memory are the first of symptoms to be seen in the case of dementia.
In the above scenario, Ronald has signed the contract when he was in a healthy period. So, the contract would be legal and enforced because a healthy person had signed it.
Answer:
From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.
Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.
Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.
Cross between ddRR (duncy) x DDrr (rutabaga)
Gametes - dR x Dr
F1 progeny - DdRr
Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.
The answer you may be looking for perhaps is Histone.
Cells differentiate in order to create cells that perform specific functions.
