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. Find out the genotype of parent pea plants.

• A. Tt × tt
• B. TT × Tt
• C. tt × tt
• D. Tt × Tt

Hint:

A 1:1 tall to dwarf ratio results from a Tt × tt monohybrid cross.

Answer 1

The Correct Option is A

A Tt (heterozygous tall) crossed with tt (homozygous dwarf) gives a 1:1 ratio of tall (Tt) and dwarf (tt) offspring. This matches the given phenotype ratio.
