A very large population of desert pupfish living in a closed basin varies in their tolerance to salinity.  Individuals with at least one dominant copy of a factor known as “halorenal factor S”* have the ability to survive very high salinity water by producing salt crystals in their kidneys and excreting them.  Individuals who are homozygous recessive have reduced survivability, but still manage to reproduce in the spring when winter runoff dilutes the salty water.   Which Hardy-Weinberg conditions would likely be met, and which would not, and why? Choose only one of the “Met” or “not met” boxes, and defend your choice.   Condition Met? Not met? Why? Keep this short and simple and within the box No mutations       Random mating       No natural selection       Large pop size       No gene flow       *halorenal factor S, though totally plausible, is totally invented by me.
