The production of egg and sperm cells is necessary for sexual reproduction because —
it increases the number of chromosomes so that the gametes can combine, giving the organism a complete set of chromosomes
it increases the number of developing offspring
it decreases the number of developing offspring
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 the process that diagram 2 represents?
cell division that occurs in reproductive structures of an organism
cell division that occurs in the repair process of damaged skin cells
occurs in all cells of the body system
process prior to the first stage of cell division
The greatest amount of genetic variation occurs in offspring that reproduce —
sexually through fission
sexually through meiosis
asexually through mitosis
asexually through budding
The steps of crossing over during meiosis are shown in the diagram. What is the significance of crossing over in Meiosis I?
Crossing over ensures that the four daughter cells produced at the end of Meiosis II have the original number of chromosomes in each cell.
Crossing over ensures that the two daughter cells produced at the end of Meiosis I have half the original number of chromosomes in each cell.
Crossing over ensures that the same combination of alleles remains in each of the four daughter cells at the end of Meiosis II.
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 in the original cell.
Which of the following could result if meiosis did not occur in the process of sexual reproduction?
Chromosomes would no longer contain genetic information.
Chromosome number would increase with each generation.
Chromosomes would not be copied exactly.
Chromosome number would decrease with each generation.

The diagram shows a cellular process that occurs in organisms. What is this process called?
Meiosis
Mitosis
Cloning
Budding
The diagram represents a change in composition of homologous chromosomes. This change is most likely the result of the process called-
Heterozygous
Crossing over
Mutation
Mitosis
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.
Daughter cells produced when cells undergo mitosis are genetically _______, and daughter cells produced when cells undergo meiosis are genetically _______.
perfect; flawed
diverse; identical
flawed; perfect
identical; diverse
Gametes must be haploid because-
gametes are small and can hold only the haploid number of chromosomes
the gametes chromosomes will be replicated prior to cell division
two gametes will unite during fertilization to create a diploid cell
fertilization results with a haploid zygote
