Question

A dihybrid cross between tall plant with round seeds and short plant with wrinkled seeds, in $F_1$ generation will produce plants______________.

• A. Hybrid for tall and round seeds
• B. Hybrid for tall and wrinkled seeds
• C. Hybrid for short and round seeds
• D. Pure for tall and round seeds

Answer 1

The correct option is A Hybrid for tall and round seeds

In a dihybrid cross, plants with two observed traits are considered for breeding; here, the two traits are the height of the plant and the seed shape, where the tall and round seeds are considered the dominant traits, while the other being the recessive. Dihybrid cross between homozygous individuals, one having dominant traits and the other having recessive traits, often leads to the production of heterozygous hybrids progeny that exhibits dominant phenotypes. Since, the dominant phenotypes are tall and round seeds, the $F_1$ progeny would be a hybrid with tall and round seeds.
