how can we produce recombinant meiosis
Answers
Answer:
In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles.
Explanation:
During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.

Explanation:
In modern genetic analysis, the main test for determining whether two genes are linked is based on the concept of recombination. Recombination is observed in a variety of situations but, for the present, let’s define it in relation to meiosis. Meiotic recombination is any meiotic process that generates a haploid product with a genotype that differs from both haploid genotypes that constituted the meiotic diploid cell. The product of meiosis so generated is called a recombinant. This definition makes the important point that we detect recombination by comparing the output genotypes of meiosis and the parental input genotypes The input genotypes are the two haploid genotypes that combined to make the genetic constitution of the meiocyte, the diploid cell that undergoes meiosis.
