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

Mark the correct statement (with respect to the Mendelian dihybrid cross where the two parents differed in two pairs of contrasting traits : seed color and seed shape).

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

Pea seeds with BB alleles have round seeds and large strach grains ,While seeds with bb alleles have wrinkled seeds with small strach grains.Work out the cross between these two parents .Explain the phenotypic ratio of the progeny with respect to seed shape and the starch gain size of the progeny produced.

A pea plant with round seeds having large starch grains is crossed with another pure pea plant with wrinkled seeds having small starch grains. The F_(1) heterozygotes formed are self pollinated. What is the phenotypic ratio of plants with round seeds and intermediate starch grains to plants with wrinkled seeds and larger starch grains expected in F_(2) generation.

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

In a typical mendellian cross which is a dihybrid cross, one parent is homozygous for both recessive traits. In the F_(2) generation, both parental combinations and recombination appear. The phenotypic ratio of parental combination appear. The phenotypic ratio of parental combinations to recombinations is

In a dilhybrid cross where two parents differ in two pairs of contrasting traits like seed colour yellow (YY) and seed colour green (yy) weith seed shapewrikled (rr) the number of green colo0ured seeds (yy) among sixteen products of F_(2) generation will be

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
