Answers:
a.
b.
c.
d.
e.
f.
g.
h.
i.
j.
k.
Interphase
The chromosomes in the nucleus of the cell make identical copies of themselves.
The chromosomes move toward and line up along the center of the cell, called the equator.
The nuclear membrane disappears and the chromosomes become distinct.
Mitosis
New nuclear membranes form around each of the two sets of chromosomes, and the cell divides
into two daughter cells.
Prophase, metaphase, anaphase, and telophase.
Daughter cells
Microtubules
Division of the nucleus of the cell (usually followed by the division of the cell itself)
The microtubules pull one set of chromosomes to one side of the cell and an identical set to the
opposite side of the cell

Genetics: Sentence Correction
Each sentence has a bold term that does not belong in that sentence, but does belong in one of the other
sentences. Correct each sentence by writing the proper bold term.
1. The study of the inheritance of traits is called meiosis.
2. When one gene expresses itself over another, the former gene is said to be the DNA gene.
3. Your behavior and physical appearance is referred to as your mutation.
4. The genes that you are carrying in your cells are referred to as your dominant.
5. The process by which a chromosome makes an identical copy of itself is called heredity.
6. When one gene expresses itself over another gene, the latter gene is said to be the sex-linked trait
gene.
7. The process of cell division resulting in daughter cells, each of which contains one half of the
normal number of chromosomes, is called replication.
8. Chromosomes are made of material called phenotype.
9. When a chromosome does not make an accurate copy of itself, the result is called a genotype.
10. When a sperm cell (which carries chromosomes from the father) fertilizes an egg cell (which carries
chromosomes from the mother), the resulting cell is said to be albino.
11. The X and Y chromosomes are called the genes.
12. Chromosomes are comprised of hundreds of sex chromosomes.
13. The normal number of chromosomes in a human body cell is 23.
14. A trait or disorder that is inherited through the sex chromosomes is called a color blindness.
15. An example of a sex-linked disorder is recessive.
16. The number of chromosomes carried in human sperm and egg cells is 46.
17. The organism that, as a result or a mutation, cannot produce pigment for skin, hair, or eyes is called
a zygote.
