4
characteristics that an organism has
traits
What part of the cell is responsible for breaking down and digesting things?
lysosomes
What type of cell undergoes meiosis?
Gamete cells
During which phase of mitosis do spindle fibers first form?
prophase
stage of mitosis in which replicated chromosomes condense and nuclear membrane dissociates
prophase
a recessive trait which is expressed only when two copies of the gene are present
dominant trait
What part of the cell serves as the intracellular highway?
endoplasmic reticulum
What type of cell are sperm cells?
Haploids
What is condensed genetic material called?
chromatids
stage of mitosis in which replicated chromosomes align at the center of the cell
metaphase
a trait that is expressed when an organism has two recessive alleles
recessive trait
Which of the following would you NOT find in a bacterial cell?
golgi apparatus
What type of cell is a stomach cell?
Diploid
During which phase does the number of chromosomes briefly double?
Anaphase
phase of mitosis where sister chromatids separate and daughter chromosomes migrate to opposite poles of the cell
Anaphase
How many genes does it take to cause a characteristic?
at least two
outermost layer of cells in plants, bacteria, fungi, and many algae that gives shape to the cell and protects it from infection
cell wall

What is the final phase of mitosis?
Telophase
phase of mitosis where nuclear membrane reforms and the spindle fibers disappear
telophase
different forms of a gene
