Solution
The correct option is A 1 : 2 : 1
A monohybrid cross is a mating between two individuals with different alleles at one genetic locus of interest.The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). Parents- Tt x TtGametes- T, t T, tOffspring- TT, Tt, Tt and ttPhenotype- Tall, Tall, Tall and DwarfGenotypic Ratio- 1 : 2 : 1Phenotypic ratio- 3 : 1
