These ages suggest that after the collision of the South China and Indochina blocks, dextral shearing deformation initiated along the Dien Bien Phu fault in the Jurassic, significantly earlier than previously thought. In order to better understand the fault’s activity, this study reports new 40Ar/39ArAr40/Ar39 geochronological data for mica schists and mylonites from several areas along the Dien Bien Phu fault, showing 40Ar/39ArAr40/Ar39 ages of 194–212 Ma for mica schists and 158–198 Ma for mylonites. It does not store any personal data.AbstractThe NNE-SSW-trending Dien Bien Phu fault, which dextrally displaces the NW-SE-trending Song Ma suture, in northwestern Vietnam, is widely considered one of the most seismically active faults in Indochina.

Principles of Inheritance and Variation.New Questions and Answers and Forum Categories If F 2 males are mated with homozygous right coiling females, there is no segregation and all their progenies are right coilers, but if they are mated with homozygous left coiling female’s only left coilers are produced. But 3: 1 ratio appears in F 3 and not in F 2. The F 2 females of either cross (right coiler) when mated with males of any genotype produce at an average right coilers and left coilers in 3: 1 ratio. In the same way offspring of left coiling mother are left coilers even if they carry dominant genes for right coiling. What do focal mechanism beach ball diagrams describe A focal mechanism, or beachball, is a graphic symbol that indicates the type of slip that occurs during an earthquake: strike-slip, normal, thrust (reverse), or some combination. The offsprings whose mothers are either homozygous or heterozygous for right coiling are right coilers even if they are homozygous for sinistrality (left coiling). In this case F 1, x F 1, cross also yields only dextral coils.įrom these experiments it becomes clear that coiling of snails is not determined by individuals’ own genes but by those of mother. The reciprocal cross (dextral ♂ x sinistral ♀) produces F 1, progeny that are all left coiler. However, in the F 1, x F 1, cross (i.e., inbreeding), all the F 1 snails are also dextral. In the cross dextral ♀x sinistral ♂ all the F, progeny have dextial coils implying that dextral is dominant over sinistral.
