A) synapsis of homologous chromosomes
B) crossing over of homologous pairs of chromosomes
C) alignment of pairs of homologous chromosomes along the middle of the cell
D) the division of cells at telophase

Question

Quizplus · Accepted Answer

Mendel's law of independent assortment is based on the alignment of pairs of homologous chromosomes along the middle of the cell during metaphase I of meiosis. Independent assortment occurs because the orientation of each homologous pair is random, meaning that either homologous chromosome can end up at either pole of the cell during anaphase I. This leads to a variety of possible combinations of alleles in the resulting gametes.
