Question

Crossing between long pea plants ( \(\text{LL}\)) and dwarf plants ( \(\text{tt}\)) shall yield the following generation:

• A. All long plants
• B. All dwarf plants
• C. Half long and half dwarf plants
• D. Three fourth long and one fourth dwarf plants

Hint:

In Mendelian genetics, a dominant allele will mask the effect of a recessive allele. In this case, the dominant allele \( L \) for long plants will determine the phenotype.

Answer 1

The Correct Option is A

In this cross, we are crossing a homozygous long pea plant (\( \text{LL} \)) with a homozygous dwarf pea plant (\( \text{tt} \)).
- The F1 generation will inherit one allele from each parent.
- The offspring will all have the genotype \( \text{Lt} \), where \( L \) represents the dominant allele for long pea plants, and \( t \) represents the recessive allele for dwarf pea plants.
- Since the long trait (\( L \)) is dominant over the dwarf trait (\( t \)), all F1 plants will be long.
Thus, the correct answer is (A) All long plants.
