Question

Genetic recombination occurs due to
A.fertilization and meiosis
B.mitosis and meiosis
C.fertilization and mitosis
D.None of these

Answer 1

Hint: During meiosis in eukaryotes, genetic recombination involves the matching of homologous chromosomes. This may be caused by data movement between chromosomes. In meiosis, non-sister homologous chromosomes pair with each other, so there is clear recombination between non-sister homologous chromosomes.

Complete answer:
Genetic recombination: Genetic recombination implies the improvement of DNA grouping by breaking and recombining chromosomes or chromosome segments. It also depicts the result of this adjustment, that is, the legacy of a new mixture of alleles that convey the recombined chromosomes to offspring. Genetic recombination is the modifier element of meiosis in most sex life, which can ensure the best separation of chromosomes. Since the recurrence of recombination corresponds to the physical separation between markers, it provides a prerequisite for genetic planning.

Recombination is also a component of several potentially fatal injuries that repair chromosomes. Genetic recombination is often used as a general term, which encompasses a variety of DNA regulation and basic subatomic cycles. Meiotic recombination is a condition of reaction that involves groupings of DNA that are combined and homologous over an extended length.

 This cycle (shown in Figure 1) is called general, true or homologous recombination. This recombination is equivalent, and the reason is that the data obtained by each trapped chromosome is the same as the data provided to the next accomplice. Since all the data on both sides of the successful breakthrough have been traded, the situation that occurs is also designated as a mixed event.

Hence the correct answer is OPTION(A)

Note: During meiosis in eukaryotes, hereditary recombination includes the matching of homologous chromosomes. This might be trailed by data move between the chromosomes. In meiosis, non-sister homologous chromosomes pair with one another so recombination naturally happens between non-sister homologous chromosomes.
