Dictionary » T » Triangle Triangletriangle 1. (Science: geometry) A figure bounded by three lines, and containing three angles. A triangle is either plane, spherical, or curvilinear, according as its sides are straight lines, or arcs of great circles of a sphere, or any curved lines whatever. A plane triangle is designated as scalene, isosceles, or equilateral, according as it has no two sides equal, two sides equal, or all sides equal; and also as rightangled, or obliqueangled, according as it has one right angle, or none; and obliqueangled triangle is either acuteangled, or obtuseangled, according as all the angles are acute, or one of them obtuse. The terms scalene, isosceles, equilateral, rightangled, acuteangled, and obtuseangled, are applied to spherical triangles in the same sense as to plane triangles. 2. An instrument of percussion, usually made of a rod of steel, bent into the form of a triangle, open at one angle, and sounded by being struck with a small metallic rod. 3. A draughtsman's square in the form of a rightangled triangle. 4. A kind of frame formed of three poles stuck in the ground and united at the top, to which soldiers were bound when undergoing corporal punishment, now disused. 5. (Science: astronomy) A small constellation situated between aries and andromeda. A small constellation near the south pole, containing three bright stars. (Science: zoology) Triangle spider, a small American spider (Hyptiotes Americanus) of the family Ciniflonidae, living among the dead branches of evergreen trees. It constructs a triangular web, or net, usually composed of four radii crossed by a double elastic fibre. The spider holds the thread at the apex of the web and stretches it tight, but lets go and springs the net when an insect comes in contact with it. Origin: L. Triangulum, fr. Triangulus triangular; tri (see Tri) _ angulus angle: cf. F. Triangle. See Angle a corner. Please contribute to this project, if you have more information about this term feel free to edit this page Results from our forumPlants  geneticsYou know that the number of offspring is shown by Pascal's triangle, right? For two alleles you have 1 : 2 : 1 For three alleles 1 : 3 : 3 : 1 For four 1 : 4 : 6 : 4 : 1 etc. So, if 4 in 1000 are 12 and 36 cm tall, that means that every in 250 plants ...

Plants  genetics4 in 1000 is the same as 1 in 250, which corresponds to 1 : 8 : 28 : 56 : 70 : 56 : 28 : 8 : 1 (from the Pascal's triangle http://en.wikipedia.org/wiki/Pascal%27s_triangle ) that is 9 options for 24 cm difference (36  12), thus the consequtive steps are of 3 cm. Thus 27 cm will ...

Nomenclature/designation question... (C to T) in an SRY gene which would be the correct designation for the mutant allele? A) sry^m (^=superscript) B) sry^gln C) SRY*Gln2Ter D) SRY*(triangle)6fs *I've ruled out C and D because D would be for deletion mutation and C is just wrong, but I am struggling to chose between A and B....any ...
