Question

question 40
tall is dominant to dwarf in pea plants. if two dwarf pea plants were crossed, their offspring will be
o all medium height
o 3/4 tall and 1/4 dwarf
o all tall plants
o all dwarf plants

Explanation:

Step1: Determine the genotype of dwarf plants

Since tall (T) is dominant to dwarf (t), dwarf plants have the genotype tt.

Step2: Analyze the cross between two dwarf plants

When two dwarf plants (tt × tt) are crossed, using the Punnett square method:

Gametes of Parent 1	Gametes of Parent 2
t	tt
t	tt

All offspring will have the genotype tt.

Answer:

all dwarf plants
