Biology Topic 11

Question 1

Meiosis

Answer 1

The process of cell division that results in the production of new cells each containing half of the number of chromosomes of the original cell.

Question 2

Crossing Over

Answer 2

Physical exchange of genetic material between homologous chromosomes. Results in new combinations of maternal and paternal alleles/genes along the chromosome.

Question 3

Independent Assortment

Answer 3

Maternal and Paternal chromosomes line up at the metaphase plate at random. This creates new combinations of maternal and paternal chromosomes in gametes.
