Question:
Mendel collected 1064 seeds from a cross between tall and dwarf garden pea plants. From this, 787 grew tall and 277 grew dwarf. This represents ___________ cross.

Show Hint
A 3:1 phenotypic ratio in the F\textsubscript{2} generation is the hallmark of a monohybrid cross.

Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the given data.
The total number of seeds obtained is 1064. Out of these, 787 plants are tall and 277 plants are dwarf. The ratio approximately comes out to be 3 : 1.
Step 2: Relating the ratio to Mendelian crosses.
A monohybrid cross involves a single pair of contrasting traits and produces an F\textsubscript{2} phenotypic ratio of 3:1.
Dihybrid crosses show a 9:3:3:1 ratio, which is not observed here.
Step 3: Conclusion.
Since only one character (height) is involved and the ratio matches a monohybrid cross, the correct answer is (D) Monohybrid.
