The division of the cytoplasm following mitosis to form two new cells is called?
Mitosis
Cytokinesis
Cancer
Tumor supression - ANSWER-Cytokinesis
Which of the following is the correct order of events in mitosis?
- Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the mitotic
spindle. The nucleus reforms and the cell divides. Cohesin proteins break down and the sister chromatids
separate.

John has alkaptonuria; it "runs in the family". John and his grandmother are both homozygous for
alkaptonuria. John's grandmother has two brothers and a sister. One of the brothers had alkaptonuria
and his daughter is John's mother. Based on this information, John's parents are:
Not carrying the alkaptonuria gene.
Both heterozygous for the alkaptonuria gene.
Both homozygous for the alkaptonuria gene.
There isn't enough information. - ANSWER-Both heterozygous for the alkaptonuria gene.
The observable traits expressed by an organism are described as its:
Zygote
Alleles
Genotype
Phenotype - ANSWER-Phenotype
Half of the gametes produced by an organism with the genotype Aa will receive the A allele, while half
will receive the a allele. This is a demonstration of:
,3|Page
independent assortment
mutation
random fertilization
segregation - ANSWER-segregation
Which of the following is true about genes that are located on different chromosomes?
These genes are inherited independently of each other.
Only the dominant alleles of these genes tend to be inherited together.
These genes are always inherited together.
These genes are more likely to undergo mutation. - ANSWER-These genes are inherited independently of
each other.
A recessive trait will be observed in individuals that are homozygous for that trait. - ANSWER-
homozygous
What are the types of gametes that can be produced by an individual with the genotype AaBb?
Aa, Bb
AA, aa, BB, bb
AB, Ab, aB, ab
AB, ab - ANSWER-AB, Ab, aB, ab
How many different types of gametes could an organism with the genotype AABbCc produce?

Genetic inheritance is being studied in a certain species of plant in which orange flower color (O) is
dominant to white (o) and round leaf shape (S) is dominant to oval (s). A true-breeding orange-flowered,
round-leaved male plant (Plant A) is mated with a true-breeding white-flowered, oval-leaved female
plant (Plant B) to produce dihybrid offspring plant (Plant C). Assuming normal Mendelian genetics and
independent inheritance of these two traits, which gametes might be produced by Plant C?
OoSs
OS
oS
Both OS and oS
Both OoSs and OS - ANSWER-Both OS and oS
Daughter cells produced by mitosis:
are genetically identical to the parent cell
are only created in females
divide the cytoplasm into four parts
cause cancer - ANSWER-are genetically identical to the parent cell
Besides growth, what must happen before a cell divides?
The cytoplasm divides into four parts
Gene mutation
Cancer
DNA replication - ANSWER-DNA replication
If John marries someone who is heterozygous for alkaptonuria, then which of the following statements is
true? Remember alkaptonuria is a recessive disorder.
