Rounded seeds ( dominant trait ) were crossed with wrinkled seeds ( recessive trait ) .
(i) What type of seeds will be produced in `F_(1)` generation ? (ii ) By self - pollination in `F_(1)` seeds what percentage of seeds will be rounded shape in `F_(2)` generation ? Explain with diagram .

If a round, green seeded pea plant (RR yy) is crossed with wrinkled, yellow seeded pea plant, (rr YY) the seeds production in F_(1) generation are

In the cross YYRR x yyrr, the number of green coloured seeds in F_(2) generation is

In the cross YYRR xx yyrr, the number of green coloured seeds in F_(2) generation is

A person first crossed pure-bred pea plants having round-yellow seeds with pure-bred pea plants having wrinkled-green seeds and found that only A-B type of seeds were produced in the F_(1) generation. When F_(1) generation pea plants having A-B type of seeds were cross-bred by self-pollination, then in addition to the original round-yellow and wrinkled-green seeds, two new varieties A-D and C-B type of seeds were also obtained. (a) What are A-B type of seeds ? (b) State whether A and B are dominant traits or recessive traits. (c) What are A-D type of seeds ? (d) What are C-B type of seeds ? (e) Out of A-B and A-D types of seeds, which one will be produced in (i) minimum numbers, and (ii) maximum numbers, in the F_(2) generation ?
