A, B, D are three independently assorting genes with their recessive alleles a, b, d respectivley. A cross was made ebtween individual of AabbDD genotype with aa bbdd. Find out the type of genotypes of the offspring produced.

In peas, tallness is dominant over dwarfness and red colour of flowers is dominant over the white colour. When a tall platn bearing red flowers was pollinated with dwarf plant bearing white flowers, the different phenotypic groups were obtained in the progeny in number (a)Tall, red - 138 (b)Tall, white - 132 (c)Dwarf, red - 136 and (d)Dwarf, white - 128. Mention the genotypes of the two parents and of the four offspring types.

Two genes 'A' and 'B' are linked. In a dihybrid cross involving these two genes, the F_1 heterozygote is crossed with homozygous recessive parental type (aa bb). What would be the ratio of offspring in the next generation?

A solid wood piece is made up of two pieces joined at right angles. The face ABCDEFA is the uniform cross section. Assuming all the angles A,B,C,D,E and F to be right angles, find the volumes of the piece

Find the current in the wire for the configuration shown in Fig. EP 6.19. Wire PQ has negligible resistance. B is the magnetic field is coming out of the paper theta is a fixed angle made by PQ travelling smoothly over two conducting paralel wire separated by a distance d.

ASSERTION TYPE QUESTIONS : These questions consist of two statements each, printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses. A. If both Assertion and Reason are true and Reason is correct explanation of Assertion B. If both Assertion and Reason are true but Reasou is not correct explanation of Assertion. C. If Assertion is true but Reason is false. D. If both Assertion and Reason are false. Assertion : Individuals produced by asexual reproduction are genetically similar to parents. Reason: Asexual reproduction involves only mitotic divisions.

The vertices of a quadrilateral are points A (- 4, 3), B (0, 0), C (4, 0) and D (0, 3). Find the lengths of its sides and point out what type of quadrilateral is it ?
