Conclusion
The identification of potential allele frequency differences among
familial crosses can link specific genotypes to important fitness
traits. Although only a small number of crosses are presented in
this pilot study produced from the
mixing of five adult colonies, our findings suggest that selective
breeding has measurable effects on the genomic diversity of the
resulting offspring. This was apparent in the significant differences in
genetic variants and phenotypes associated with stress tolerance when
exposed to varying temperatures. These results are in line with studies
demonstrating the influence of recent immigrants having significant
influence on allele frequency shifts.
