Imagine the same cross of two triple heterozygous pea plants with tall stems and axial purple flowers (genotype TtAaPp). Using the rules of probability (and not a Punnett square), determine what proportion of offspring will have dwarf stems and axial purple flowers?

Explanation:

Here ,

The allele "T" represents the tall height trait of pea plant

and allele "t" represents the short height trait of pea plant

The allele "A" represents the axial flower trait of pea plant

and The allele "a" represents the non axial flower trait of pea plant

The allele "P" represents the purple color trait of pea plant

and allele "p" represents the purple color trait of pea plant

Genotype of parent is  Tt Aa Pp

Two parents with genotype Tt Aa Pp and Tt Aa Pp are crossed.

Probability of getting a dwarf stem is

Tt * Tt

TT, Tt, Tt, tt

Probability of getting a axial flower

Aa * Aa

AA, Aa, Aa, aa

Probability of getting a  Purple flower

Pp *  Pp

PP, Pp, Pp, pp

The probability of getting a offspring with dwarf stems and axial purple flowers

b. regulated is the actual answer to your question.
