During which phase of meiosis does the nuclear membrane reform around the chromosome?

• Interphase
• Anaphase I
• Telophase II
• Prophase I

Homologous chromosomes move to opposite poles of a cell during...

• Anaphase II
• Anaphase I
• Metaphase I
• Telophase I

Meiosis II is similar to mitosis in that...

• homologous chromosomes synapse
• DNA replicates before division
• The chromosome number is reduced
• Sister chromatids separate during anaphase

At which stage of meiosis do chromatids separate?

• Metaphase I
• Metaphase II
• Anaphase I
• Anaphase II

Which 2 cells would be more genetically similar to each other?

• 2 gametes produced by the same person

• 2 somatic (body) cells produced by the same person

• 2 eggs produced by the same woman

• 2 sperm produced by the same man

If a diploid organism has a genome consisting of 22 chromosomes, its gametes will have ___ chromosomes

• 44
• 22
• 11
• 20

Which of the following types of cells in humans are considered diploid?

• egg cell

• somatic (body cells)

• sperm cell

• gamete

The correct number of chromosomes is maintained during fertilization in sexual reproduction by-

• meiosis, which reduces the chromosome number of the gamete by one half
• chromosomes being copied immediately after fertilization of the gametes
• mitosis, which maintains the number of chromosomes in the daughter cells
• half of the chromosomes being destroyed immediately after fertilization of the gametes.
