Predict the genotypic and phenotypic outcome (offspring) of a cross between two heterozygous tall pea plants?

The genotype of the cross is 1 : 2 : 1 ( TT : Tt : tt )

The phenotype of the cross is 3 : 1 ( Tall : Dwarf )

Explanation:

Given:

Cross between two heterozygous tall pea plant

Let the allele of a tall pea plant be represented by T and for dwarf be t

In heterozygous condition, the genotype would be Tt

Cross between Tt X Tt is shown in the diagram inserted.

According to the cross performed:

The genotype of the cross is 1 : 2 : 1 ( TT : Tt : tt )

The phenotype of the cross is 3 : 1 ( Tall : Dwarf )

answer: c.

explanation:

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
