WebIn mitosis, both the parent and the daughter nuclei contain the same number of chromosome sets—diploid for most plants and animals. Meiosis employs many of the same mechanisms as mitosis. However, the starting nucleus is always diploid and the nuclei that result at the end of a meiotic cell division are haploid. WebChromosome segregation has been studied by the mutation of genes that are involved in mitosis followed by observation of chromosome behavior. For example, by studying kinetochore mutants, scientists have been able to elucidate both the structure of the kinetochore and its function. how are diamonds manufacturedWebSep 2, 2014 · Background Allopolyploids generally undergo bivalent pairing at meiosis because only homologous chromosomes pair up.
