An entire chromosome that codes for a trait

Chemical messengers in your brain that code for a trait

If black fur is dominant and white fur is recessive, what are the possible offspring of two black mice bred together?

any of the above are possible, depending on the parents' genotypes

What are the two laws identified by Mendel?

Law of Segregation and Law of Independent Assortment

Law of Genetics and Law of Probability

Which of the following is the best definition for MEIOSIS?

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

the process of two haploid cells uniting

the counting of chromosomes within a diploid cell

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.

Each DNA gets pull to the opposite sides of the cell

DNA lines up in the middle of the cell and DNA attaches to spindle fibers

centrioles and spindle fibers appear

Mitosis results in the formation of...

Two identical cells with all of the original chromosomes

Two different cells with half of the original chromosomes

Four identical cells with all of the original chromosomes

Four different cells with half of the original chromosomes

What is the purpose of mitosis?

To allow cells to divide for growth, repair, and renewal

To increase the surface area of a cell

For increasing genetic variation within a species

To allow for DNA replication and protein synthesis

Why is it important for the chromosomes to condense during mitosis?

to facilitate chromosome movement without tangling and breaking

to facilitate cytokinesis and formation of a cell plate

to facilitate microtubule spindle formation

In mitosis , the two resulting cells are

identical to the starting cell and identical to each other.

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.

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

In order for genetic information to be transferred into daughter cells.

In order for the cell to be able to increase in size.

In order for the DNA to be contained in the nucleus.

In order for the cell to re-order the DNA sequencing in the new cells.
