The linkage map of X - chrommosomes of fruitfly has 66 units , with yellow body gene (y) at one end and bobbed hair (b) gene at the other end . The recombination frequency between these two genes (y and b) should be

A scientist performed the gene mapping experiments in maize. He mapped the gene on chromosomes on the basis of % crossing over between different genes. One map unit corresponds to one % crossing over or recombination. Te genes showing more than 50% recombination were not supposed to be linked on same chromosome. In crossing over studies on maize, scientist observed the following % crossing over between A B, C, d- between. A and D 10% between A and C 3% between genes C and D 7% between genes A and B 5% , and between genes C and B 8% on the basis of above observation find out the correct sequence of tenes Alt B, C, and D on chromosomes :-

(i) Two cylindrical pipes are each of length L = 30 cm . One of them contains hydrogen and the other has oxygen at the same temperature. The ends A, B, C and D of the pipes are fitted with flexible diaphragms. The diaphragms A and C are set into oscillations simultaneously using the same source having frequency f = 600 Hz . Calculate the difference in phase of oscillations of the diaphragms D and B if it is known that the speed of sound in hydrogen at the temperature concerned is 1200 m//s . (ii) The air column in a pipe closed at one end is made to vibrate in its second overtone by a tuning fork of frequency 440 Hz . The speed of sound in air is 330 m//s . P_(0) is mean pressure in the pipe and DeltaP_(0) is maximum amplitude of pressure variation. Neglect end correction. (a) Find the length L of air column. (b) What is amplitude of pressure variation at the middle of the column? (c) What is maximum and minimum pressure at the closed end?
