Meiosis worksheet
What event must take place during interphase before a cell proceeds to division?
DNA replication
At which stage of meiosis 1 are the cells diploid and at which stage are they haploid?
Diploid: prophase, metaphase, and anaphase Haploid: telephase after the cell has split
In meiosis 1, during anaphase 1, which structures separated- homologous chromosomes or sister chromatids?
Homologous chromosomes
At which stage in meiosis 1 do the pairs of homologous chromosomes come together?
Late prophase 1
What do spermatids eventually become?
Mature sperm
During fertilization which two cells come together?
Mature sperm and secondary oocyte
Where did each of the cells come from that started meiosis 2?
Meiosis 1
Before fertilization what happens to the secondary oocyte?
Oocyte proceed to meiosis 2
What is the name given to the cells produced at the end of meiosis 1 in females?
Secondary oocyte
What is the name given to the cell Produced at the end of meiosis 1 in males?
Secondary spermatocyte
In what type of organs are rhe cells that enter meiosis 1 found?
Sex organs
What two structures make up a single replicated chromosome?
Sister chromatid in prophase 3
In meiosis 2, during anaphase 2, which structures separated- homologous chromosomes or sister chromatids?
Sister chromatids
At the end of meiosis 2 in males what cells are produced?
Spermatids
Once the chromosomes have formed a pair what are they called?
Tetrads
Which of the statements below correctly describes the relationship between the cells at the end of meiosis 2 and the original cell?
The new cells have one copy of half of the genetic information in the original cell.
Describe the relationship between cells at the end of telophase 1 and the original cell?
The new cells have two copies of half of the genetic information in the original cell.
At the end of the meiosis are four daughter cells. Are they haploid or diploid? Explain your answer in a complete sentence.
They are haploid because they contain a sister chromatid from each homologous pair. It contains a set of genes.
At the end of meiosis 1, two cells have been produced. How many replicated chromosomes are in each of these cells?
Two
