Question

One of the traits that Mendel studied in the pea plant is plant height. Tall plants are dominant with respect to dwarf plants. If the gene for this trait is denoted by the letter "T", then the genotype of a dwarf pea plant is ___.

Answer 1

tt

Step-by-step explanation:

Tall plants are dominant with respect to dwarf plants.. If the gene for this trait is denoted by the letter "T"

i.e Let the dominant traits for Tall pea plants be T

Let the traits for The dwarf pea plants be t

To determine the genotype of the dwarf pea plant, where the dwarf traits will be expressed:

We have to cross the Tt × Tt

T t

T TT Tt

t Tt tt

We have offspring ( TT, Tt, Tt, tt )

TT = Dominant tall pea plant

2 Tt = Two heterozygous tall pea plant.

tt = dwarf pea plant.
