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).

What is a test cross? Show a monohybrid test cross using a Punnet square and give the phenotypic ratio.

By using Punnett square, schematically represent the hybrid cross experiment conducted by Mendel using seed color and seed shape of pear as characters.

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

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 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.
