18 Questions
What is the result of meiosis II?
Two haploid daughter cells
During which phase of meiosis do tetrads line up at the metaphase plate?
Metaphase I
What occurs in synapsis during meiosis?
Homologous chromosomes loosely pair up
In which phase of meiosis do pairs of homologous chromosomes separate?
Anaphase I
What is the end result of crossing over during meiosis?
Exchange of DNA segments
How many chromatids are present in a chromosome during Metaphase II of meiosis?
Two
Which process is responsible for the production of gametes with a haploid set of chromosomes?
Meiosis
In human somatic cells, how many pairs of homologous chromosomes are present?
23 pairs
Which of the following statements about sexual reproduction is correct?
Offspring have unique combinations of genes inherited from two parents.
What is the term used to describe the ordered display of pairs of chromosomes from a cell?
Karyotype
Which of the following statements about meiosis is correct?
It involves two successive nuclear divisions.
What are the sex chromosomes in humans called?
X and Y
What is the key difference between sister chromatids in metaphase II compared to metaphase I?
In metaphase II, sister chromatids are no longer genetically identical due to crossing over in meiosis I.
What happens to the sister chromatids during anaphase II?
The sister chromatids separate and move towards opposite poles as individual chromosomes.
What is the main purpose of meiosis?
To reduce the number of chromosome sets from diploid to haploid for gamete production.
What is the key difference between mitosis and meiosis in terms of genetic variation?
Mitosis produces genetically identical cells, while meiosis produces genetically distinct cells.
What is the ploidy of the daughter cells produced at the end of meiosis?
Haploid
What process occurs during telophase II of meiosis?
Nuclei form, and chromosomes begin decondensing.
This quiz compares asexual reproduction, where a single individual passes genes to its offspring, to sexual reproduction, where two parents give rise to offspring with unique gene combinations. Learn about clones, genetic diversity, fertilization, and meiosis in sexual life cycles.
