anaphase I crossing-over
a phase of meiosis the exchange of
I during which DNA segments
homologous pairs of between homologous
chromosomes move to chromosomes; occurs
opposite sides of the cell in prophase I of
meiosis

anaphase II DNA nucleus
a phase of meiosis deoxyribonucleic
II during which the acid; genetic DNA
centromere splits material within
and chromatids the nucleus
move to opposite
sides of the cell

egg
centromere fertilization sperm
the point on the the joining of an
chromosome where centromere egg and sperm to
the two chromatids form a zygote that
are held together develops into a
new organism zygote

from Mother from Father
chromatids homologous
two identical chromosomes
copies of a a maternal and paternal
chromosome chromosome that are
the same length and
have genes for the same
chromatids characteristics homologous pair

meiosis
chromosome cellular process that parent cell
a structure of chromosome
produces sex cells
coiled DNA and (egg and sperm) daughter
proteins that cells
which contain half
forms in the cell’s the number of
nucleus prior to proteins DNA chromosomes of
mitosis sex
the parent cell cells
