Question

Tt alleles are pair of:

• A. Homozygous long
• B. Heterozygous long
• C. Homozygous dwarf
• D. Heterozygous dwarf

Hint:

In genetics, the combination of different alleles results in heterozygous, while identical alleles form homozygous pairs.

Answer 1

The Correct Option is D

Step 1: Understanding the alleles.
The alleles T and t represent the traits for the plant. The capital letter T usually represents the dominant trait (long), and the lowercase t represents the recessive trait (dwarf).
Step 2: Determine the type of pair.
The combination of one capital T and one lowercase t results in a heterozygous combination (Tt), with T being dominant. Hence, the correct description is "Heterozygous dwarf."
Final Answer: \[ \boxed{(D) \; Heterozygous \; dwarf} \]
