Using punnett square show the `F_2` results of a dihybrid cross where the pure breed parents have contrasting traits with reference to seed shape and seed colour in Pisum Sativum. Give the phenotypic ratio.

The ratio of F2 generation of a dihybrid cross having pure , monohybrids , dihybrids plants is

A homozygous pea plant with round seed coat and yellow cotyledons is crossed with another homozygous pea plant having wrinkled seed coat and green cotyledons. Give the dihybrid phenotypic ratio with the corresponding phenotypes.

A homozygous pea plant with round seed coat and yellow cotyledons is crossed with another homozygous pea plant having wrinkled seed coat and green cotyledons. Give the dihybrid phenotypic ratio with the corresponding phenotypes.

Given below is a schematic diagram showing Mendel's Experiment on sweet pea plants having axial flowers with round seeds (AARR) and Terminal flowers with wrinkled seeds (aarr). Study the same and answer the questions that follow : Give the phenotypic ratio of F_2 progeny.

Give an example of a plant where the F_(2) Progeny of a monohybrid cross has same genotypic and phenotypic ratios.

If a true breeding homozygous pea plant with green seed and axial flower as dominant characters is crossed with a recessive homozygous pea plant with yellow seeds and terminal flowers, then what would be the: Phenotypic distribution ratio in F_2 population?

The given Punnett's square represents to Pattern of inheritance in a dihybrid cross where yellow (Y) and round (R) seed condition in dominant over white (y) and wrinkled (r) seed condition {:(" YR Yr yR yr"),("YR F J N R"),("Yr G K O S"),("yR H L P T"),("yr I M Q U"):} A plant of type 'H' will produce seeds with the genotype identical to seeds produced by the plants of

A true breeding pea plant homozygous for axial violet flowers is crossed with another pea plant with terminal white flowers (aavv). (a) What would be the phenotype and genotype of F_(1)" and "F_2 generations? (b) Give the phenotype ratio of F_2 generations. (c) List the Mendel’s generalisations that can be derived from the above cross.

(a) Atrue breeding pea plant, homozygous for inflated green pods is crossed with another pea plant with constricted yellow pods (ffgg). What would be the phenotype and genotype of F_1" and "F_2 generations ? Give the phenotype ratio of F_2 generation. (b) State the generalisation proposed by Mendel on the has 18 of the above mentioned cross.

(a) Explain a monohybrid cross taking seed coat colour as a trait 1n Pisum sativum. Work out the cross upto F generation. (b) State the laws of inheritance that can be derived from such a cross. (c) How is the phenotypic ratio of F2 generation different in a dihybrid cross?
