Genetic diversity

[jbennetth]

If a study population has lost genetic diversity, does this mean that the population has lost heterozygosity and that the population is also not in Hardy-Weinberg equilibrium?

[JackBean]

well, you probably won't have clones of only one specimen (i.e. all the specimen won't have exactly the same genome). At least not, if is it due to some natural processes and not in lab Thus you may have some heterozygotes.
Shortly after the lost, the population won't be in equilibrium, but after few generations it should be restored
