So, almost like two Interphases then, at least the DNA replication portion
of it? So Meiosis results in 4 "zygotes" instead of 4 haploid daughter
cells. cool.
Michael, I'll see what I can dig up on Rhamphotyphlops and either post it or
e-mail it to you privately. Its become quite an invasive species. I've
caught it in Florida and have seen specimens from Hawaii, though it is
native to Asia (not sure exactly where it is native... not sure we can
really tell given it's near global distribution at this point... it even
occurs in the basements of the historic buildings on State Street in
Boston!!! dirt floors... it eats termites!... tends to travel around in
flower pots from tropical plant stores).
