Sequencing of a pine tree population reveals four variants of a particular SNP.Eighty percent (80%)of the trees have the G,15% the A,3% the T,and 2% the C variant.What is the genetic diversity of the pine tree population with respect to this SNP?

Genetic diversity measures the variation in a population's genes or genomes. In this question, we are given the frequency of four alleles (G, A, T, and C) of a SNP in a pine tree population. The genetic diversity can be calculated using the formula:

D = 1 - Σ(p_i)^2

Where 'p_i' is the frequency of the i-th allele, and the summation is taken over all alleles.

In this case, we have:

D = 1 - [(0.8)^2 + (0.15)^2 + (0.03)^2 + (0.02)^2]
D = 1 - [0.64 + 0.0225 + 0.0009 + 0.0004]
D = 1 - 0.6638
D = 0.3362 or 33.62%

Therefore, the answer is C) 33.6%.
