Question

What mechanism results in a mixture of maternal and paternal homologues moving to each daughter cell during meiosis 1? (Choose all statements that help explain this.) Spindle fibers from each cell pole attach randomly to maternal and paternal homologues of a homologous pair Homologous pairs of chromosomes orient randomly in the cell Spindle fibers of a given cell pole attach to either ALL maternal or ALL paternal homologues Spindle fibers of a given cell pole sort through homologous chromosome pairs to select a random combination of homologues.

Explanation / Answer

The homologous chromosomes are assigned random orientations to the haploid daughter cells, so each of the daughter cells are a mixture of maternal and paternal homologues moving to each daughter cells during meiosis. The random distribution of the maternal and paternal homologoes leads to the reassortment of the chromosomes in the daughter cells. This might also result from the random attachment of spindle fibres to the maternal and paternal homologoes of a homologous pair.

Hence, the first two options are correct.
