A population of 600 plants contain 294 AA, 252 Aa, and 54 aa individuals. AA and Aa plants produce purple flowers while aa plants produce white flowers. What are the frequencies of the following? Allele A
Allele a
purple-flowered plants
white flowered plants
genotype AA
genotype Aa
genotype aa

If both the AA and Aa individuals have Allele A, then the proportion of individuals with Allele A = (294 + 252)/600. However, if you want the proportion of times that A occurs in the gene pairs, this is ([2*294] + 252)/(2*600).

Proceed in a similar way with the other problems.

Explanation:

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.
