Meiosis

The chromosomes that pair up during meiosis, are called __________ chromosomes.  

• homozygous 
• asexual
• homologous
• genes

The process of crossing over occurs in what phase of meiosis?

• anaphase 1
• prophase 1
• prophase 2
• telophase 1

This image shows chromosomes during Prophase 1. Which of the following correctly describes the process shown?

• segregation of sister chromatids
• condensation and segregation of alleles
• mutationin which the DNA content of the gene is altered
• crossing - over in which alleles are exchanged

Each chromosomes pairs with its corresponding homologus chromosome to form a tetrad

• Metaphase I

• Telophase I & Cytokinesis

• Prophase I

• Anaphase II

 Cell created at the end of meiosis are best known as

• somatic cells
• gamete cells
• skin cells
• diploid cells

Unlike mitosis, meiosis results in the formation of

• Two genetically identical cells.

• Four genetically different cells.

• Four genetically identical cells

• Two genetically different cells
