In a cross between two heterozygous tall pea plants (Tt x Tt), what is the expected ratio of tall to short offspring?
- 1:1
- 2:1
- 3:1
- 4:0
📝 Detailed explanation
Using a Punnett square, the genotypes are TT, Tt, Tt, and tt.TT and Tt are tall, while tt is short.
This results in 3 tall plants for every 1 short plant.
