Corals live in symbiosis with algae called zooxanthellae

2014 Coral Bleaching Event in Hawaii

Lanikai Beach (12/21/15) Observation: Some coral colonies bleach, some do not. Question: Why is there inter-colony variation in bleaching response? Hypothesis: Some corals have heat- tolerant zooxanthellae. Prediction: If…then genetic techniques should reveal the presence of heat- tolerant zoox in unbleached colonies Porites compressa

Lanikai Beach (12/21/15) Observation: Some coral colonies bleach, some do not. Question: Why is there inter-colony variation in bleaching response? Hypothesis: Some coral genotypes are more heat tolerant than others. Prediction: If…then genetic analysis of the corals should reveal alleles at loci whose presence are correlated with the bleaching response. Porites compressa

Homework Post your prediction on Twitter. If your prediction has already been posted, then either “Favorite”, “Retweet”, or both. You may decide that someone else’s prediction is better than your, then Favorite or Retweet. Be able to explain why you think a particular prediction is good. You need to know this.
