where sperm mature
Draw the phase where chromosomes are visible for the first time.
picture of prophase
Explain crossing over and when does it occur?
chromosomes exchange information creating variation; prophase 1
How many daughter cells are made in each process. Are they haploid or diploid?
Meiosis - 4 ; haploid
Mitosis - 2 ; diploid

fertilization, zygote, blastula, implantation
Which phase include the cell almost pinching together and separating into two cells?
Telophase
What is the difference between a cell in Metaphase 1 and Metaphase 2?
Metaphase 1 - homologous pairs in the middle
Metaphase 2 - chromatids line up the middle
