Question

Which conclusion follows from the tall and dwarf pea plant monohybrid cross?

पर्याय

• Dwarfness is dominant; tallness is recessive

• Tallness and dwarfness are both recessive

• Tallness and dwarfness have genotype \[Tt\] only

• Tallness is dominant; dwarfness is recessive

Answer 1

All F1 plants with genotype \[Tt\] are tall, showing that tallness is dominant. Dwarfness appears only in the \[tt\] F2 outcome, so it is recessive.
