Question

In the event of crossing of a homozygous tall plant with a dwarf plant, plants in the F2 generation would be

• A. All homozygous dwarf
• B. All heterozygous tall
• C. One homozygous tall, one homozygous dwarf and two heterozygous tall
• D. Two tall and two dwarf

Answer 1

The correct option is C One homozygous tall, one homozygous dwarf and two heterozygous tall

Crossing for F${}_1$ : TT X tt
F${}_1$ offspring : Tt
Selfing of F${}_1$: Tt X Tt
Gametes: T, t T, t
Fusion: Tt (Heterozygous tall), TT (Homozygous tall), Tt (Heterozygous tall) and tt (Homozygous dwarf).
