Comparing mitosis and meiosis Transitional Reasoning Practice

Questions

1. 1.

   A cytologist examining dividing cells from an animal species with a diploid number of $2n = 16$ observes two cells at metaphase under a microscope. Cell P displays 8 bivalents (tetrads) aligned along the equatorial plate, whereas Cell Q displays 16 individual replicated chromosomes aligned along the equatorial plate. Based on these observations, which of the following correctly compares the divisions that Cell P and Cell Q are undergoing?

   • A) Both divisions will produce diploid daughter cells, but only Cell P generates genetic variation through crossing over.
   • B) Cell P will complete a reductional division leading to genetically distinct haploid cells, whereas Cell Q will complete an equational division producing genetically identical diploid cells.
   • C) Cell P will separate sister chromatids during its upcoming anaphase, whereas Cell Q will separate pairs of homologous chromosomes.
   • D) Cell P produces daughter cells with identical gene combinations to the parent, whereas Cell Q generates recombinant daughter cells.
