Crossing Over and GeneticMappingDuringmeiosis the two chromosomes in eachhomologous pair exchange segments through a process called crossing overThisprocess of crossing overand the resultingrecombin.

DNA is highly compacted: DNA + histone proteins = . chromatin. Meiosis . MEIOSIS. The production of offspring by sexual reproduction includes the fusion of two gametes, each with a complete haploid set of chromosomes. . Gametes are formed from specialised diploid cells. This specialised kind of cell division that reduces the chromosome number by half results in the production of haploid daughter cells. This kind of division is called . CfE Advanced Higher Biology.
