Question

What are the advantages of crossing over and recombination?

Answer 1

Advantages of crossing over and recombination:

1. Genetic recombination is the interchange of genetic material between organisms that results in the development of children with features that are distinct from those of either parent.
2. Crossing over refers to the exchange of genetic material or chromosome segments between non-sister chromatids in meiosis.
3. Recombination provides advantages for sexual organisms such as:
   1. Crossing over provides an inexhaustible store of gene variability in sexually reproducing organisms
   2. It plays an essential role in the process of evolution
   3. The process of recombination helps in promoting genetic variation in the gene pool.
   4. It leads to construction of genetic maps and production of new gene combination.
