To allele for pea comb (P) in chickens is completely dominant to the allele for single comb (p) . The alleles for black feature colour (B), and white feature colour (B') show codominance, so that BB' individuals possess blue features. If thickness heterozygous for both pairs of genes are matedm what proportion of offspring are expected to be pea combed and white feathered ?

On a piece of paper certain odd number of horizontal lines at equal distances are drawn. An equal number of vertical lines at equal distances are also drawn, forming rectangles. The rectangles are coloured black or white, set alternately. Three coins are put at random in these rectangles. Let p be the probability of having two coins in rectangles of the same colour and the third in a rectangle of the other colour, and p' be the probability of having all the coins in the rectangles of the same colour. If p : p' =16 : 5 then find the number of horizontal lines drawn on the paper.

If four o' clock plants, the gene for red flower colour (R) is incompletely dominant over the gene for white flower colour (r), hence the plants heterozygous for flower colour (Rr) have pink flower. What will be the ratio of offsprings in a cross between the red flowers and pink flowers ?

Ten people are sitting in two parallel rows. G,H,J,K and M are sitting in row 1 facing south. V,W,X,Y and Z are sitting in row 2 facing north . The person sitting in row 1exactly faces the person sitting in row 2. they like five different colours, red , white , blue, green and black. exactly two people like the same colour and the persons who like the same colour don't sit in the same row. W sits at one of the extreme ends. there is only one person who sits between W and the one who faces the person who like red colour. K sits to the immediate right of the person who like red colour. There is one person who sits between W and X. X like red colour. Number of persons who sits to the right of X is same as that of number of person who sits to the left of J. The person who likes Green colour sits immediate left of X. two people sit between Z and V. Z sits somewhere to left of V. Z faces the one who like green colour. One of the people who like black colour is an immediate neighbour of the one who like blue colour. M sits left of G. M is an immediate neighbour of H. H faces the person who sits to the immediate right of the person who like black colour. Y and H doesn't like black colour. there is only one person between K and the one who like white colour. In a certain way, K is related to X, V is related to J, in the same way Y is related to who among them following person ?
