WebAlleles for these genes tend to segregate together during meiosis, unless they are separated by crossing-over. Crossing-overoccurs when two homologous chromosomes exchange genetic material during meiosis I. The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing-over. WebApr 19, 2024 · “Shuffling combinations of alleles through recombination generates the diversity upon which natural selection acts.” Recombination is therefore important for two main reasons: Imagine two chromosomes with genes A and B. On one chromosome you might have a “good” (beneficial) A allele and a “bad” (deleterious) B allele. WebCrossing over and NCGC both shuffle combinations of alleles, and this degradation of linkage disequilibrium (LD) has major evolutionary consequences, ranging from immediate effects on nucleotide diversity to long-term consequences that shape genome evolution, species formation and species persistence. church shirts
