Easy
Which process is responsible for generating gametes in sexually reproducing organisms?
Clonal Division
Meiosis
Mitosis
Binary Fission
Meiosis is the specialized cell division that produces gametes with half the number of chromosomes. This reduction is essential to maintain the species-specific chromosome number upon fertilization.
How many daughter cells are produced at the end of meiosis from one diploid cell?
Four
Three
Two
Eight
Meiosis produces four daughter cells, each containing half the number of chromosomes of the original cell. This halving is crucial for forming haploid gametes used in sexual reproduction.
During which phase of meiosis does crossing over occur?
Metaphase I
Telophase I
Anaphase II
Prophase I
Crossing over takes place during prophase I, where homologous chromosomes pair up and exchange segments of genetic material. This event increases genetic diversity among the gametes.
What defines homologous chromosomes?
Chromosomes produced by mitosis
Chromosomes that carry the same genes in the same order
Chromosomes that are identical in every way
Chromosomes that do not pair during meiosis
Homologous chromosomes have the same genes arranged in the same order, although they might carry different alleles. Their pairing during meiosis is essential for crossing over and proper segregation.
Which of the following best describes the outcome of meiosis?
Generation of four genetically distinct haploid cells
Creation of genetically identical haploid cells
Formation of one polyploid cell
Production of two identical diploid cells
Meiosis produces four haploid cells that are genetically distinct due to recombination and independent assortment. This genetic variability is a cornerstone of sexual reproduction.
Medium
Which phase of meiosis is characterized by the pairing of homologous chromosomes and crossing over?
Prophase I
Metaphase I
Telophase I
Anaphase I
During Prophase I, homologous chromosomes come together and crossing over occurs. This step is vital for introducing new genetic combinations.
What is the role of the synaptonemal complex in meiosis?
It separates sister chromatids
It facilitates the pairing and recombination of homologous chromosomes
It breaks down the nuclear envelope
It duplicates DNA
The synaptonemal complex holds homologous chromosomes together during prophase I, enabling precise alignment and recombination. This structural scaffold is key to ensuring proper crossing over.
During which stage do homologous chromosomes separate in meiosis?
Prophase I
Anaphase I
Metaphase I
Anaphase II
Homologous chromosomes are separated during Anaphase I, which results in the halving of the chromosome number. This separation is essential for producing haploid cells.
Which process, unique to meiosis, contributes to genetic diversity?
Budding
Crossing over
Binary fission
Mitosis
Crossing over is a unique feature of meiosis where homologous chromosomes exchange segments of DNA. This process greatly enhances genetic variation among the resulting gametes.
How many daughter cells are typically produced from a single meiotic division in animals?
Three
Two
Eight
Four
A complete meiotic process produces four daughter cells, each with half the chromosome number of the original cell. This reduction is key to ensuring stable chromosome numbers in sexually reproducing organisms.
What does the term 'reduction division' refer to in meiosis?
The process that reduces the chromosome number by half
A phase in which cells double their DNA
The division that increases the chromosome number
The process of cell separation in mitosis
The term 'reduction division' describes how meiosis halves the chromosome number from diploid to haploid. This is achieved by separating homologous chromosomes during meiosis I.
At the end of meiosis II, what is true about the chromosomes in the daughter cells?
Chromosomes double in number
Each chromosome consists of a single chromatid
All chromosomes are duplicated
Chromosomes still exist as pairs of sister chromatids
Following meiosis II, the sister chromatids separate so that each chromosome is composed of a single chromatid. This final step produces haploid cells with the correct structure.
Which event is primarily responsible for the creation of new allele combinations during meiosis?
Spindle formation in metaphase I
DNA replication in interphase
Chromosome condensation in prophase II
Crossing over during prophase I
Crossing over in prophase I enables the exchange of genetic material between homologous chromosomes, creating new allele combinations. This mechanism is a major source of genetic variation in sexually reproducing organisms.
What mechanisms during meiosis contribute to genetic variation among resulting gametes?
Transcription and translation
Independent assortment and crossing over
DNA replication errors only
Mitosis and binary fission
Independent assortment randomly distributes homologous chromosomes, and crossing over exchanges segments of DNA. Together, these processes generate significant genetic diversity among gametes.
In which phase of meiosis is the nuclear envelope reformed?
Metaphase II
Prophase I
Anaphase I
Telophase II
During Telophase II, the nuclear envelope is reassembled around the separated chromatids, signifying the end of the meiotic process. This regeneration marks the formation of completely separate haploid nuclei.
Hard
Which molecular event initiates the process of crossing over in meiosis?
Centromere duplication
RNA polymerase activation
Programmed double-strand breaks by Spo11
Telomere shortening
The initiation of crossing over is triggered by programmed double-strand breaks in the DNA, induced by the enzyme Spo11. This controlled damage allows for the exchange of genetic material between homologous chromosomes.
What is the consequence of nondisjunction during meiosis I?
Enhanced genetic recombination
No effects on the gametes
Gametes with abnormal chromosome numbers
Increased number of nucleoli
Nondisjunction in meiosis I results in the failure of homologous chromosomes to separate properly. This error leads to gametes with an abnormal number of chromosomes, a condition known as aneuploidy.
In which stage are chiasmata most clearly observed, and what do they indicate?
Anaphase I; they indicate points of chromosome separation
Diplotene of prophase I; they indicate sites of crossing over
Telophase I; they indicate reformation of the nuclear envelope
Metaphase II; they indicate spindle attachment sites
Chiasmata become visible during the diplotene stage of prophase I as the homologous chromosomes begin to separate slightly. They mark the precise locations where crossing over has taken place.
Which checkpoint ensures that homologous recombination is properly completed in meiosis?
The pachytene checkpoint
The spindle assembly checkpoint
The DNA damage checkpoint
The G2/M checkpoint
The pachytene checkpoint monitors the process of homologous recombination and synapsis during prophase I. It ensures that any errors in these processes are corrected before the cell proceeds further in meiosis.
How does meiosis contribute to evolution at the population level?
By preventing mutations entirely
By generating genetic diversity through independent assortment and crossing over
By doubling the chromosome count in gametes
By producing genetically identical daughter cells
Meiosis produces genetic diversity through mechanisms such as independent assortment and crossing over. This diversity is a crucial factor in natural selection and the evolution of populations.
