UPDATED ACTUAL Exam Questions and
CORRECT Answers
A diploid has 12 chromosomes. How many chromosomes does the haploid cell of that organism
have? - CORRECT ANSWER -6
A tree has 44 chromosomes in its gametes. How many chromosomes would the leaf/somatic cell
have? - CORRECT ANSWER - 88
What is the significance of crossing over in Meiosis I? - CORRECT ANSWER - Crossing
over ensures that the chromosomes in the four daughter cells produced at the end of Meiosis II
will have a different assortment of genes than the corresponding chromosomes
Gametes must be haploid because...? - CORRECT ANSWER - Two gametes will unite
during fertilization to create a diploid cell
The production of egg and sperm cells is necessary for sexual reproduction because...? -
CORRECT ANSWER - It reduces the number of chromosomes so the gametes can
combine, giving the organism a complete set of chromosomes
Which of the following best describes meiosis?
-It is carried out in all tissues that require cell replacement
-It happens in all tissues except the brain and spinal cord
-It occurs only in cells in the reproductive structures of the organism
-It is the first stage of mitosis - CORRECT ANSWER - It occurs only in cells in the
reproductive structures of the organism
Crossing Over - CORRECT ANSWER -
, There are a total of ________ chromosomes in human sperm or egg cells. - CORRECT
ANSWER - 23
Which of the following could result if meiosis did not occur in the process of sexual
reproduction?
-Chromosomes would not be copied exactly
-Chromosome number would decrease with each generation
-Chromosomes would no longer contain genetic information
-Chromosome number would increase with each generation - CORRECT ANSWER -
Chromosome number would increase with each generation
A cell has 16 chromosomes. After meiosis, how many chromosomes will the daughter cells
have? - CORRECT ANSWER -8
Meiosis - CORRECT ANSWER -
There are ________ cells produced in meiosis. - CORRECT ANSWER -4
A male shark has 40 chromosomes in each of its sex cells. How many would be present in its
body cells? - CORRECT ANSWER - 80
Unlike mitosis, meiosis in male mammals results in the formation of...? - CORRECT
ANSWER - Four haploid gametes
The chromosomes that pair up during meiosis, are called ___________ chromosomes? -
CORRECT ANSWER - Homologous
The process of crossing over occurs in what phase of meiosis? - CORRECT ANSWER -
