What is the diploid number for humans? What is the haploid number for humans?

• Diploid: 46, Haploid: 23

• Diploid: 23, Haploid: 46

• Diploid: 44, Haploid: 22

• Diploid: 48, Haploid: 24

What is meiosis?

• A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell

• A process of cell division that results in two daughter cells each having the same number of chromosomes as the parent nucleus

• A phase in the cell cycle where the cell grows and replicates its DNA

• A process by which cells become specialized in structure and function

What is the main goal (end result) of meiosis?

• To produce genetically identical cells

• To produce four genetically unique gametes

• To repair damaged cells

• To produce energy for the cell

What is a zygote and how is it formed?

• A zygote is formed when sperm and egg combine.

• A zygote is a type of cell that forms during mitosis.

• A zygote is a cell that results from the division of a fertilized egg.

• A zygote is a specialized cell that forms tissues in plants.

What are homologous chromosomes?

• Chromosomes that are identical in size and shape, carrying the same genes at the same loci.

• Chromosomes that are different in size and shape, carrying different genes.

• Chromosomes that are identical in size but not shape, carrying different genes at different loci.

• Chromosomes that are different in size and shape, carrying the same genes at the same loci.

Describe the process of crossing over.

• Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I

• Crossing over is the process of cell division that results in two daughter cells.

• Crossing over is the replication of DNA during the S phase of the cell cycle.

• Crossing over is the separation of sister chromatids during mitosis.

What two events in Meiosis lead to genetic variation (unique gametes)?

• Crossing over and independent assortment

• DNA replication and cell division

• Mitosis and cytokinesis

• Fertilization and mutation
