Question

Which of the following varieties of rice has been produced by the hybridisation of Oryza japonica and O. indices?
A. Jagannath
B. Aruna
C. ADT-37
D. Reimei

Answer 1

Hint: Hybridization is the process of crossing two genetically distinct individuals to produce a third individual with a distinct set of qualities, which is often favoured. Plants from the same species easily cross and produce viable offspring.

Complete answer:
Interbreeding between individuals of different species (interspecific hybridization) or genetically diverse individuals from the same species (intraspecific hybridization) is the process of hybridization (intraspecific hybridization). Hybridization produces viable, partially fertile, or sterile offspring.
Plant hybridization is the process of creating a hybrid by crossing two genetically different parents. Polyploid offspring are common as a result.
Hybridization is the process of creating new genotypes by crossing two genetically distinct individuals. A cross between a parent 1 with the genetic makeup BB and a parent 2 with the genetic makeup bb, for example, creates hybrid children with the genetic makeup Bb.
Gregor Mendel's historic trials with garden peas were based on hybridization. Crossing plants with contrasting or complementing features is required for inheritance research.
Hybridization is a powerful evolutionary force since it can result in
(1) increased intraspecific genetic diversity across participating populations.
(2) the emergence of new species.
(3) the extinction of species due to genetic assimilation.
 (4) the development of extremely invasive genotypes.
Hybridization is the process of creating a double-stranded nucleic acid from two complementary strands of DNA in molecular biology (or RNA). It's known as nucleic acid hybridization in specific.

ADT-37 is a cross of Oryza Japonica and Oryza Indices that is inter-varietal. So, the correct answer is option C.

Note: Natural hybridization, which is the norm in cross-pollinated plants, has played a vital role in the development of new genetic combinations. It's a frequent method for generating genetic diversity.
