What is synapsis?

• Synapsis occurs during mitosis to separate sister chromatids.
• Synapsis is the fusion of gametes during fertilization.

Multiple Choice

What happens when chromosomes cross over during meiosis?

• Chromosomes duplicate and become identical.
• Chromosomes are destroyed and cannot be used again.
• Chromosomes remain unchanged and separate normally.
• Chromosomes exchange genetic material, leading to genetic recombination.

Multiple Choice

During Meiosis I, chromatids separate.

• True

• False

Match

Match the following phases with their definitions.

• Prophase I

• Metaphase I

• Anaphase I

• Telophase I

• Cytokinesis I

Chromosomes condense and

Tetrads line up at the cell's equator.

Homologous chromosomes are pulled apart to opposite poles.

Nuclear membranes reform around each set of chromosomes.

The cytoplasm divides, resulting in two daughter cells.

Multiple Choice

Why can't a Y-chromosome carry traits?

• A Y-chromosome carries all genetic traits equally for both sexes.
• Y-chromosomes are responsible for all inherited traits in males.
• A Y-chromosome can't carry traits but they are not expressed in females.

• A Y-chromosome cannot carry traits because it has limited genetic information and size.
