Meiosis
two-stage cell division in
which the chromosome number of
the parental cell is reduced by half
haploid
refers to the number of
chromosomes in a gamete
diploid
refers to twice the number of
chromosomes in a gamete
homologous chromosomes
paired chromosomes similar in
shape, size, gene arrangement, and
gene information
tetrad
a pair of homologous
chromosomes, each with two
chromatids
synapsis
the pairing of
homologous chromosomes
crossing over
the exchange of
genetic material between two
homologous chromosomes
nondisjunction
the failure of a pair
of homologous chromosomes to
separate properly during meiosis
polyploidy
a condition in which an
organism has more than two
complete sets of chromosomes
trisomy
the condition in which
there are three homologous
chromosomes in place of a
homologous pair
monosomy
the condition in which
there is a single chromosome in
place of a homologous pair
karyotype chart
a picture of
chromosomes arranged in
homologous pairs
polar body
a small haploid cell produced during oogenesis (egg formation) in meiosis
ootid
the haploid cell produced near the end of oogenesis (egg formation) after meiosis II is complete
oocyte
a female gamete (egg cell) that develops through oogenesis, the process of meiosis in females
