In peas, tallness (T) is dominant over shortness (t). If one parent is hybrid tall and the other is purebred short, predict the expected genotypes and phenotypes in the first generation of 100 plants. Find the answer using Punnett Square

Answer 1

Hey!!!

Answer:

Tt-Hybrid tall, and, tt-pure dwarf

Parents: Tt × tt

↓ ↓ ↓ ↓

Gametes: T t t t

F₁: Tt ; Tt ; tt ; tt

Phenotypic ratio: (Tall:Short) : 1:1

.

Genotypic ratio: (Tt:tt) : 1:1
