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. WebHow are they different? Meiosis and mitosis are both cell division processes. During cell division, they follow the same prophase, metaphase, anaphase, and telophase processes. They differ in how Meiosis involves sexual reproduction, whereas mitosis is an asexual process. Meiosis occurs in higher life forms like humans and animals.
