I believe that both reserves, 1 and 2, were designed equally efficient in promoting heterozygosity and conservation of population alleles. Although the two reserves differ slightly, they had similar outcomes. Reserve 1 had a lower heterozygosity than Reserve 2, yet preserved more alleles. This was due to the presence of subpopulations. The subpopulations restrict the interactions between the ferrets, decreasing the heterozygosity. The conservation of alleles was due to the subpopulation dynamic. The subpopulations decrease the negative effect of the loss of an allele on the entire population due to the sectional divisions. Reserve 2 had higher heterozygosity than Reserve 1, yet lost more alleles. This was due to the single unit design of the reserve. The single unit allowed for more ferrets to interact and breed, increasing heterozygosity. Yet, the single unit was affected more when an allele was loss, due to the lack of division in the reserve.

The only suggestion I have is
The only suggestion I have is, instead of saying the reserves differ slightly, specify how they differ.
Sounds Awkward
Rephrase "were designed equally efficient".
a lower heterozygosity------ "lower heterozygosity rates"
Otherwise, great paragraph!
