Regent Review Reproduction and Development

Mitosis is _____ reproduction because all offspring (known as daughter cells) have the DNA from only one parent and are clones of that parent

• sexual
• asexual
• fertilization
• haploid

the single cell that is made when sperm and egg combine their genetic material (DNA)

• zygote
• gamete
• somatic
• haploid

This type of cellular reproduction is important because it allows organisms to grow and also repairs damaged tissue by replacing dead or injured cells

• mitosis
• meiosis
• fertilization

In mitosis, the two resulting cells are

• different from the starting cell and identical to each other.
• different from the starting cell and different from each other.
• identical to the starting cell and different from each other.
• identical to the starting cell and identical to each other.

What occurs in meiosis but NOT mitosis

• crossovers between homologous chromosomes

• crossovers between sister chromatids

• spindle formation

• chromosome number is conserved

What process occurs in BOTH mitosis and meiosis

• crossovers in prophase I

• separation of sister chromatids

• anaphase II

• division of two genetically identical nuclei

A type of cell division where the cell divides into two copies

• Vegetative propagation

• Budding

• Fragmentation

• Binary Fission

Which of the following is the best definition for MEIOSIS?

• the process of two haploid cells uniting

• the counting of chromosomes within a diploid cell

• a two-step process that reduces the number of chromosomes in half such that there is only one copy of all the chromosomes

• the equational division of a cell into two identical copies

Which of the following are CORRECT observations about the differences between MITOSIS and MEIOSIS? (Check all that apply.)

• Mitosis produces cells that identical to the parent cell.

• Meiosis produces cells that have half the number of chromosomes as the parent cell.

• All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.

• In both types of cell division, the chromosomes are only duplicated once.

• Only in Mitosis, do you see chromosomes pair up to form a tetrad.
