If a sperm cell contains 8 chromosomes, it comes from an animals that has ____ chromosomes.
4
8
12
16
24
A cell contains 12 chromosomes at the end of meiosis I, how many chromosomes will the daughter cells contain at the end of meiosis II?
3
6
During which stage of meiosis does crossing-over occur?
Prophase I
anaphase I
telophase I
Prophase II
anaphase II
What is the importance of crossing-over?
It provides extra genetic material for the daughter cells.
It increases the likelihood that daughter cells contain different genetic material.
It produces the proteins that are associated with DNA in chromosomes.
It increases chromosome condensation.
It separates the homologous chromosomes.
Synapsis is when a duplicated chromosome pairs with its homologue to form a tetrad.
Between meiosis I and meiosis II a second round of DNA replication occurs.
A cell that contains 2 sets of chromosomes is said to be in number.
At the end of meiosis females produce healthy egg cell plus polar bodies and males produce healthy sperm cells

Match the phases of meiosis with their proper discription.
Oogenesis Spermatogenesis( Oogenesis, Spermatogenesis ) is the process of making female sex cells, while oogenesis spermatogenesis( oogenesis, spermatogenesis ) is the process of making male sex cells.
