Answer:
0 additive alleles = A0B0C0D0
1 additive allele = A+B0C0D0, A0B+C0D0, A0B0C+D0, A0B0C0D+
2 additive alleles = A+B0C0D+, A+BC+D0, A0B+C+D0, A0B+C0D+, A0B0C+D+, A+B+C0D0
3 additive alleles = A+B+C+D0, A+B+C0D+, A+B0C+D+, A0B+C+D+
4 additive alleles = A+B+C+D+
In the first stages of Alzheimer’s disease, the patient
affected may experience symptoms, such as memory loss of certain events. As the
time passes, the patient may experience long-term memory loses, the patient may
also revert into being a child. Patients who has been diagnose with Alzheimer’s
