Sahil performed an experiment to study the inheritance pattern of genes. He crossed tall pea plants (TT) with short pea plants (tt) and obtained all tall plants in F1 generation.
When F1 plants were cross-pollinated with plants having tt genes, a total of 800 plants were produced. How many of these would be tall, medium height or short plants? Give the genotype of F2 generation.
उत्तर
- In the cross between Tt X tt, 400 Tall (Tt) and 400 short (tt) plants will be produced.
- 1 Tt : 1 tt
