MCQ : The pea plants produced from the seeds obtained from a cross between hybrid tall (Tt) and pure dwarf (tt) pea plants will be (a) All dwarf (b) All tall (c) 75% tall, 26% dwarf (d) 50% tall, 50% dwarf

50% tall, 50% dwarf

Explanation

When a hybrid tall (Tt) pea plant is crossed with a pure dwarf (tt) pea plant, the resulting pea plants will exhibit a phenotypic ratio of 1:1 for tall to dwarf. The genotype of the offspring will be either Tt (tall) or tt (dwarf) because the pure dwarf parent contributes only “t” alleles.
