In Pisum, yellow seed colour (Y) is dominant over green (y), and round shape of seed (R ) is dominant over wrinkled (y). Consider that these two pair of genes assort independently, then (i) What proportion of the offsprings from the cross the cross `YyRr xx yyrr` would expected to have yellow-seeded trait ? (ii) From the cross `Yyrr xx Yyrr`, how many will be pure yellow-wrinkled plants in the resulting generation ?
