Grain colour in wheat is determined by three pairs of polygenes. Following cross AABBCC (dark colour) x aabbcc (light colour), in F₂ generation what proportion of the porgeny is linkely to resemble either parent ?

The adjacent graph shows the extension () of a wire of length 1m suspended from the top of a roof at one end and with a load W connected to the other end. If the cross-sectional area of the wire is , calculate the Young’s modulus of the material of the wire.

Which is not correctly matched :

In a plant three dominant independetly assorting gene A. B and C are essential for production of purple pigment. If any of the genes or all three genes are present in recessive condition then flower is colourless Raw material  pigment A purple plant with genotype AABBCC crossed with a colourless plant with genotype aabbcc gives purple F1 hybrid. On selfing of F₁ - what proportion of coloured offspring in F₂

Consider function f(x) satisfies the relation, and differentiable for all x.

In this question, we have given two statements are like assertion and reason. The odd function is, a function such that f (−x) =−f (x) where the sign is reversed but the absolute value remains the same if the sign of the independent variable is reversed.
