Please help! punnet square and shouldn’t be hard! thank you

In the resulting offspring the correct proportions are for the genotype 1:1 and for the phenotype 1:1 (first option).

Explanation:

According to Mendel's Laws, the product of the cross between a heterozygous individual and a homozygous recessive for a character will always be a hybrid or recessive offspring as the Punnett square shows on image.

For the character -tall and short- of the pea plant:

Alleles    t         t

T           Tt        Tt

t             tt         tt

For the genotype: probabilities that in the offspring there are hybrid individuals with genotype Tt is 50% and recessive tt 50% .

For the phenotype: the probabilities of tall plants in the offspring are 50%, and 50% short plants.

A 50:50 ratio, for genotype and phenotype, is equivalent to saying that both phenotypic and genotypic ratio is 1:1.
