A pure tall Pea plant is crossed with pure dwarf Pea plant. The progeny is self-pollinated. The ratio of true breeding tall Pea plants to true breeding dwarf Pea plants shall be
The F1 progeny obtained by the crossing of pure tall pea plant with pure dwarf pea plant, is subjected to self pollination, in the next generation 1 homozygous tall 2 heterozygous tall 1 homozygous dwarf progeny are formed. The ratio exists between the homozygous tall and homozygous dwarf is 1:1.
So,the correct option is ‘1:1’.
