**Title: Understanding Genetic Recombination Through Homologous Chromosomes****Content:**One chromosome of a homologous pair carries the genes J and K. The other chromosome of the pair carries the genes j and k at corresponding loci. Crossing over results in the exchange of chromosome segments and the production of gametes with new combinations of genes. A "recombinant" type gamete resulting from this crossover might contain:- **A:** J and K- **B:** J and j- **C:** j and k- **D:** K and k- **E:** j and K**Explanation:**In the process of meiosis, homologous chromosomes can undergo a crossover, exchanging genetic material. This can create recombinant gametes that carry new combinations of alleles. In this example, the original alleles were J, K and j, k. Due to recombination, gametes with mixed alleles such as j and K can be produced, demonstrating genetic diversity.

Crossing over is found in the prophase 1 of meiosis. It produces genetic variations.

One chromosome of a homologous pair carries the genes Jam K. The othen chromosome of the pair carrieo the genes jand k at corresponding loci. Crossing results in exchange of chromosome segmut of gamutes combinations of A "recombinaut and production with genes. new type gamete resulting from this cross over might contain: A-Jand K D-K and k B-J and j E-i and K and k
