Transgenerational adaption

For selective breeding to be successful desirable traits are required to be genetically passed through generations. To test the degree of inheritance of heat tolerant traits adult colonies are bred to produce F1 and then F2 corals. Adult colonies of parent colonies are tested for the heat tolerant phenotype through heat stress experiments so that a phenotypic lineage is known for all offspring. All offspring are kept in a common nursery to reduce differential acclimatisation to different environmental conditions. At each life stage; gametes, larvae, spats, and adults the corals are tested again for their heat tolerance. This will lead us to answer the important question of how much adaptation potential is genetically controlled by the coral animal. Through answering this question of hereditability, we can then show how much intervention is required to elevate heat tolerance within a population.
