Genetics Overview
Punnett Squares
100
Is mitosis a form of asexual or sexual reproduction?
asexual
100
What are the stages of Meiosis 2?
Prophase 2, Metaphase 2, Anaphase 2, Telophase 2
100
When are sister cromatids formed?
During DNA replication
100
Is a dominant trait shown with a capital or lowercase letter?
A capital letter

In the image below, the trait for red ears in mice (R) is dominant to the trait for white ears (r). A white heterozygous red-eared father produced with a heterozygous red-eared mother. What is the probability of the offspring having white ears?
25 percent
200
What is mitosis?
The division of a nucleus to create two daughter cells.
200
What is fertilization?
The process of sexual reproduction is where male gametes join together with female gametes as one.
200
What are the three reasons that explain we don't look exactly like our parents?
Independent assortment, crossing over, and random fertilization
200
What is the difference between a monohybrid and a dihybrid cross?
A monohybrid cross only examines one trait at a time while a Dihybrid examines two at a time.
200
In the image seen below, the allele for red eyes is represented as R, and the allele for yellow eyes is represented as r. What is the probability that the offspring will have red eyes?
100 percent
400
What are the four stages of mitosis? (Not including cytokinesis)
Prophase, Metaphase, Anaphase, Telophase
400
What happens to the cell during Anaphase I
Homologous chromosome pairs separate and are pulled to opposite ends of the cell. Spindle fibers also shorten.
400
If a human diploid cell contained 46 chromosomes, how many chromosomes would a human haploid cell contain?
23 chromosomes
400
What person is known as the "father of genetics?
Gregor Mandel
400
What type of trait is seen in this punnett square
an x linked trait.
800
What does it mean for a cell to be diploid?
There are two complete sets of chromosomes in the cell.
800
What is another name for homologous chromosome pairs?
Tetrads
800
What is a karyotype?
An image of all the chromosomes in a singular cell arranged in order of size.
800
What is the law of segregation
a law that explains the fact that each gene separates from each other so that each gamete only carries one allele for each gene.
800
If Black(B) and White(W) are codominant alleles for skin color in cows. What are the possible phenotypes for this gene?
Black, White, and black white spotted/mixed
1000
What is the difference between cytokinesis in animal cells and plant cells?
During cytokinesis in animal cells, a cleavage furrow forms to pinch the cytoplasm apart. In plant cells, a cell plate forms to separate the cytoplasm.
1000
What is the difference between Meiosis 1 and Meiosis 2?
Meiosis 2 occurs in two separate cells whereas Mitosis 1 only occurs in a single cell. Also, Meiosis 1 involves homologous pairs lining up in the middle while Meiosis 2 has sister chromatids lining up in the middle and separating to opposite ends.
1000
A human was given three copies of the 21st chromosome instead of two, what is this specific mutation called?
Down's Syndrome
1000
In pea plants, seed color and shape genes are located on different chromosomes. Which law best explains why these traits are not inherited together?
the law of independent assortment
1000
In humans, there are three different types of alleles for blood type(I^A, I^B, and i). These alleles represent blood types, A, B, and O respectively. i^A and i^B are codominant whereas i is recessive to both. If a type A father and type O mother reproduce, what is the likelihood that their offspring will have type O blood?
