Tetrad: when a homologous
pair is in synapsis
Homologous pair: one

cell to create 4 new cells Centromere: connecting part
-prophase I: homologous of a chromosome
chromosomes pair, crossing Centrosome: organizes
over microtubules to provide

Crossing over: pieces of
chromosomes exchange to
increase genetic diversity
Synapsis: pairing of

before crossing over
line up (1 row)

split to opposite sides
-telophase II: nuclear
envelope assembles,

cells Independent assortment:
random alignments of
chromosomes to increase
genetic diversity
Nondisjunction: failure of
pairs to separate during
anaphase
