Inheritance of one gene (Monohybrid cross)
Mendel crossed tall and dwarf pea plant and collected all the seeds obtained from this cross. He
grew all the seeds to generate plants of first hybrid generation called F1 generation. He
observed that all the plants are tall. Similar observation was also found in other pair of traits.
Mendel self-pollinated the F1 plants and found that in F2 generation some plants are also
dwarf. The proportion of dwarf plants is 1/4th and tall plants of 3/4th.
44 / 13
