a life-cycle type in which the diploid and haploid
alternation of generations
stages alternate
the structure that forms at the cross over points after
chiasmata (chiasma)
genetic material is exchanged
proteins that form a complex that seals sister
cohesin chromatids together at their centimetres until
anaphase
exchange of genetic material between non-sister
Crossover chromatids resulting in chromosomes that incorporate
genes from both parents of the organism
Fertilization union of 2 haploid cells from 2 individual organisms
The multicellular haploid life cycle stage that
gametophyte
produces gametes
specialized cell line that produces gametes, such as
germ cells
sperm and egg
Interkinesis (Interphase II) brief period of rest between meiosis I and meiosis II
the sequence of events in the development of an
life cycle organism and the production of cells that produce
offspring

a nuclear division process that results in four haploid
Meiosis
cells
the first round of meiotic cell division; referred to as
Meiosis I reduction division because the ploidy level is reduced
from diploid to haploid
the second round of meiotic cell division following
Meiosis II meiosis I; sister chromatids are separated from each
other, and the result is four unique haploid cells
protein assemblies formed on the synaptonemal
complex that mark the points of crossover events and
recombination nodules
mediate the multistep process of genetic
recombination between non-sister chromatids
a nuclear division that produces daughter nuclei each
reduction division having one-half as many chromosome sets as the
parental nucleus; meiosis I is a reduction division
all the cells of a multicellular organism except the
somatic cell
gametes or reproductive cells
haploid cell that can produce a haploid multicellular
spore organism or can fuse with another spore to form a
diploid cell
a multicellular diploid life cycle stage that produces
sporophyte
haploid spores by meiosis
the formation of a close association between
synapsis
homologous chromosomes during prophase I
protein lattice that forms between homologous
synaptonemal complex chromosomes during prophase I, supporting
crossover
two duplicated homologous chromosomes (four
tetrad chromatids) bound together by chiasmata during
prophase I
