Joel Davenport · Answer 1

B: gametes that contain only paternal or maternal chromosome

Explanation:

During meiosis, homologous chromosome separates and sister chromatids move to opposite poles as a result of the shortening of the spindle. Since maternal and paternal chromosomes will independent separate during meiosis, this will result in the formation of gametes with either paternal or maternal chromosome and never a mixture of the two.

Paternal chromosomes will assort to give paternal gametes

Maternal chromosomes will assort to give maternal gametes

The correct option is B. The assortment will leads to formation of gametes that contain only paternal or maternal chromosomes
