What kind of cells undergo Meiosis? (Choose all correct answers.)
Gametes
Sex Cells
Sperm Cells
Somatic Cells
A cell containing two complete sets of chromosomes, one from each parent is called:
inherited.
diploid.
haploid.
homologous.
Crossing over is:
the joining of two gamete cells to produce an offspring different than both parents.
the attributes of an organism, expressed by genes and/or influenced by the environment.
a set of alleles/genes that determine the expression of characteristics or traits.
the exchange of alleles/genes between homologous chromosomes.
What is the result of a single cell going through the process of meiosis?
one identical new cell
two identical new cells
four identical new cells
four gamete cells
What is the first stage in Meiosis II?
Cytokinesis
Prophase II
Interphase II
Metaphase II
Which of the following are advantages of sexual reproduction? (Choose all correct answers.)
provides variation
allows for flexibility and adaptation in a new environment
happens quickly and produces many offspring
produces identical offspring
What would be an example of a bioethical issue?
asexual reproduction in spider plants
crossing over during prophase I
gene therapy - transferring a normal gene in place of a mutated gene
studying a model of DNA to determine what each gene codes for
What creates variation in the offspring of sexually reproducing organisms? (Choose all correct answers.)
fertilization between haploid cells
mitotic division in somatic cells
mutation
crossing over during Prophase II
What is a characteristic of asexual reproduction? (Choose all correct answers.)
offspring that are identical to their parents
undergo both meiosis and mitosis
two-parent fertilization
large number of offspring
Which type of cell division is taking place?
mitosis - the new cells have the same number of chromosomes as the parent
meiosis - the cell divides once to form four new cells
mitosis - the cells line up as homologous pairs
meiosis - the new cells have half as many chromosomes as the parent
Which type of reproduction does this type of cell division represent?
asexual
sexual
meiotic
parental
In which phase of Meiosis do cells undergo a round of DNA replication, forming duplicate chromosomes? (Choose all correct answers.)
Prophase I
Interphase I
Prophase II
Interphase II
During Prophase I, the chromosomes condense and:
sister chromatids separate and move toward opposite ends of the cell.
each chromatid lines up in the middle of the cell and spindle fibers attach to the centromeres.
each chromosome pairs with its corresponding homologous pair to form a tetrad.
the nuclear membrane forms and the cell begins to divide into two cells.
Which of the following are examples of a mutagen? (Choose all correct answers.)
What is the definition of “mutation”?
mitosis out of control, causing cancer
a change in the ribosome, causing mutated proteins
a substance that causes permanent damage to the gametes
permanently changed DNA, which alters the genetic message
