VOGABULARY
gam€togenesis
egg
sperm
polar body
Cells go through two rounds of dlvision in meiosis.
a chromosome is replicated each half is called a
2. Two chromosomes
sister chromatld
that are very similar and carry the same genes are called
homologous chromosomes
In the space beloW sketch the phases of meiosis I and II and write the name of each phase
below
it.
