Answer:

Genetic recombination is the process by which genetic material is exchanged between different chromosomes or within the same chromosome, resulting in new combinations of genes.

Genetic recombination is the process by which genetic material is exchanged between chromosomes, resulting in new combinations of genes. This occurs during sexual reproduction and contributes to genetic diversity.

Characteristics of Genetic Combination

  • Occurs During Meiosis - Genetic recombination typically takes place during meiosis, specifically in the prophase I stage when homologous chromosomes pair up and exchange genetic material through a process called crossing over.
  • Increases Genetic Diversity - By shuffling genes between chromosomes, recombination generates new genetic combinations. This increases genetic variation among offspring, which can enhance adaptability and survival in changing environments.
  • Involves Crossing Over - During recombination, segments of DNA are exchanged between homologous chromosomes. This crossing over results in chromosomes with new combinations of alleles, different from those in the parent cells.
