1, which are different in nature. Gene recombination is the combination of two different genes to form a new gene fragment. Gene mutation refers to the sudden and heritable variation of genomic DNA molecules.

2. Gene mutation is the emergence of genes from scratch, and mutation produces new genes. Gene recombination is the recombination of original genes to produce new genotypes.

3. The time of gene recombination is different. The time of gene recombination is the local exchange of non-sister chromatids of homologous chromosomes in tetrad period and the recombination of non-homologous chromosomes in late meiosis period. The time of gene mutation is between mitosis and meiosis.

Extended data:

From the molecular level, gene variation refers to the change of base pair composition or arrangement order of genes in structure. Although genes are very stable and can accurately replicate themselves during cell division, this stability is relative. Under certain conditions, a gene can also suddenly change from the original existing form to another new existing form, that is, at a site, a new gene suddenly appears to replace the original gene, which is called a mutant gene.

Gene recombination is the process of exchanging and recombining DNA fragments and forming new DNA molecules due to the breakage and connection of different DNA chains. In 1974, Vaclav Gibbard called it synthetic biology of gene recombination. 1978, he wrote in Gene magazine that restriction endonucleases will lead us into a new era of synthetic biology.
