Question

............. traits are unable to express in a hybrid.

• A. Recessive
• B. Dominant
• C. Inherited
• D. Acquired

Answer 1

Answer: (A)

Recessive

• The trait is a distinguishable feature of a character and its detectable variant. For example, tallness and dwarfness.
• The hybrid plant possesses a heterozygous condition in which genotype have both contrasting alleles such as Tt in the hybrid plant. T represents tallness and t represents dwarfness.
• Dominant character tallness (T) can be expressed in both conditions such as homozygous (TT) and heterozygous condition (Tt) but recessive character dwarfness (t) can be expressed only in homozygous (tt) condition and thus unable to express in hybrid plants.
