A village tank was traditionally a major residential water source in Bangladesh. These were excavated ponds that had supplied earth for house supports and road embankments; they were used for drinking water, bathing, irrigation, and pisciculture. Water wells began to supply a safer source of drinking water to a large part of the population, starting in the 1970s, replacing the use of village tanks for drinking water. A survey conducted in 1944-45 established that Feni subdivision had 13400 acre of tanks on 221400 acres of total land. These were thought to be approximately 8 feet in depth. Other regions of Bangladesh had fewer, but still sufficient tanks to provide a substantial potential contribution to agricultural irrigation needs.

Permanent translocation heterozygosity in Gaura biennis. "Chiasmata are terminal and chromosome disjunction is alternate so that all chromosomes and essentially all genes of each 7-chromosome “Renner” complex come to reside in the same gamete. A system of balanced lethals and incompatibility alleles prevents the formation of structural homozygotes. As a consequence of these features, the structural heterozygotes in these selfing Oenothera have the maximum amount of linkage attainable in a sexually reproducing organism."

"Renner complex - in -> complex heterozygous species (Oenothera), a group of chromosomes (and the genes which they contain) which are distributed as one unit from generation to generation" "Renner effect (Darlington 1932) - competition (= megaspore competition) among the four genetically different spores formed by one meiosis in regard to which shall form the embryo (Darlington & Mather 1949)." "Complex heterozygous" (Renner 1916) - of species (called "complex heterozygotes") heterozygous for numerous allele pairs linked to different chromosomes but segretating as a unit during meiosis. Complex heterozygotes are "interchange hybrids" heterozygous not only for one, but for two, three, four, or more reciprocal translocations. …Oenothera … During Anaphase 1, the maternal complex of chromosomes is distributed to one pole, the paternal complex to the other (from Cleland 1962) … Renner (1941)"
