Pure black colour and rough hair of guineaping is _______character,

Black colour of Bread Mould is due to

Show the result of hybridization till F2 generation between a pure black (BB) coarse haired (RR) guinea-pig and a pure white (bb) smotth haired (rr) . Guinae-pig by a cheaker board. State the conclusion one can reach from this hybridization experiment.

Cross between homozygous black rough (BBRR) guinea pig and homozygous white smooth guinea pig (bbrr) produced black and rough animals in F_(1) generation. Presuming the genes to be present on different chromosomes, the percentage of F_(2) individuals which are heterozygous for both the gene pairs would be

With the help of checker board show the type of offsprings that might be produced in a cross between hybrid black guineaping and a pure white guineaping. State the law of Segregation as proposed by Mendel.

If the squares of a 8xx8 chessboard are painted either red or black at random The probability that all the square in any column are of same colour and that of a row are alternate in colour is -

In the case of peppered moth (Biston betularia) the black-coloured from became dominant over the light-coloured form in England during industrial revolution. This is an example of

Tall(T) is completely dominant over dwarf(t). Red flower colour ( R) is incompletely dominant over white ( r), the heterozygous being pink. Plant having genotype of TrRr is self pollinated. What would be the proportion of plants with dwarf and pink characters in the progeny

Which are true about the following statements about kangaroo rats (a) They have dark colour, high rate of reproduction and excrete solide urine (b) They do not drink water, breathe at slow rate, and have their body covered with thick hair (c) The feed on dry seeds and do not require drinking water (d) They excrete very concentrated urine and do not use water to regulate body temperature
