Answer 1

Hint: In biology, a hybrid is the result of sexual reproduction combining the qualities of two organisms of different breeds, varieties, species, or genera. Hybridization is the process of using base pairing to combine two complementary single-stranded DNA or RNA molecules into a single double-stranded molecule.

Complete answer:
Hybridization is the process of an animal or plant breeding with an individual of another species or variety.
A double-stranded DNA (or RNA, or DNA/RNA) molecule can be heated to break the base pairing and separate the two strands in a reversal of this process. Many important laboratory techniques, such as polymerase chain reaction and Southern blotting, require hybridization.
The most common form of DNA is a double-stranded molecule. Hybridization is the process by which these two strands bind to one another in a complementary manner. When DNA is replicated, the new strand naturally hybridizes with the old strand. Hybridization can be used in the lab to create nucleic acid probes that can be used to screen for the presence or absence of certain DNA molecules or RNA molecules in the cell.
The steps involved in hybridization are:
1. Selection of parents
2. Evaluation of parents
3. Emasculation
4. Bagging
5. Tagging
6. Pollination
7. Harvesting and Storage of F1 seeds.

Thus, the correct answer is option C: Selection, emasculation, bagging, crossing, distribution.

Note:
Human impact on the environment, such as habitat fragmentation and species introductions, has a significant impact on hybridization. The genetics of populations undergoing introgressive hybridization is difficult to conserve as a result of such effects. Humans have been introducing species to environments all over the world for a long time, both intentionally for purposes such as biological control and unintentionally, such as with individual escapes. Introductions, including hybridization, can have a significant impact on populations.
