Question

In a monohybrid cross, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would be the predicted result of crossing two intermediate (Tt) parent plants?

Answer 1

Answer:

Genotype:

• 1/4 = 25% TT.
• 2/4 = 1/2 = 50% Tt
• 1/4 = 25%  tt

Phenotype:

• 3/4 = 75% Tall plants
• 1/4 = 25% short plants

Ratios

• The genotypic ratio of the progeny is 1:2:1
• The phenotypic ratio of the progeny is 3:1

Due to technical problems, you will find the complete explanation in the attached files.
