The main features which are directly derived from our experiments can be explained assuming the formation of a heterogeneous multiple lamellar population arrangement.
In native Palearctic populations arrangements O3+4+2 and O3+4+8 are restricted to the Mediterranean region (the likely area from which the original American colonists derived [ 36]) and are not involved in latitudinal clines [ 35].
Third, perhaps because of the adolescent age of our population, if arrangements were made to participate in our study, about half of the adolescents were no-shows at the set time and date for their assessment.
In the original Palaearctic populations chromosome arrangements O3+4 and O3+4+8 have a higher frequency at lower latitudes than arrangement Ost, and the converse is true a higher latitudes [ 35, 36].
In Japan, population statistics system categorizes living arrangements only according to the number of persons who live together and have the same family name.
There was also some evidence for the development of population differentiation within arrangements and particularly the inverted arrangement.
In 18 Argentina populations where arrangement 2jz3 is present, its relative frequencies range from 0.5 to 31.5% with an average of ∼8% [65].
This analysis reveals discontinuities in morphological differentiation in relation to the populations' geographical arrangement.
A few states have extreme segregation -- physically separate housing units where youthful offenders have no contact with the adult population -- or arrangements with the state juvenile facility where they spend a few years there and are transferred to prison on their 18th birthdays".
