Staring from Genetic transfer and recombination: I need the definitions, please

Repair of UV induced damage: Photolyases: Nucleotide excision repair: Methylases: Xeroderma Pigmentosum: Identifying Mutants: Identifying chemical carcinogens: The Ames test: Genetie transfer and recombination: Genetic recombination: Crossing over: Vertical gene transfer: Horizontal gene transfer: Donor cell: Recipient cell: Transformation in bacteria: Griffith's experiment: Streptococcus pneumoniae: Smooth strain (encapsulated): Rough strain (nonencapsulated): Competence: Conjugation in bacteria: F factor (fertility factor): Hfr (high frequency of recombination) cell: Transduction in bacteria: Bacteriophage (phage):

Answer 1

Genetic recombination is the process of exchange of genetic material between two chromosomes or between two cells or even between two organisms.

Crossing over is the process of exchange of genetic material between non sister chromatids of homologous chromosomes during prophase 1 of meiosis 1.

Vertical gene transfer is the process of transfer of genetic material from one generation to another, that is from parents to progeny.

Horizontal gene transfer is the process of transfer of genetic material from one organism to the other, provided, both the organisms belonging to the same generations or both the organisms belong to different species but are not parents and progeny of each other.
