Question
During a monohybrid cross involving a tall pea plant with a dwarf pea plant, the offspring populations were tall and dwarf in equal ratio. Work out a cross to show how it is possible.
Solution
50% of dominant traits and 50% of recessive traits during a monohybrid cross can be obtained by a test cross between a homozygous pea plant and a heterozygous pea plant.
