meiosis
unequally
During cytokinesis 1 and 2 how is the cytoplasm of the original cell divided up
synapsis
During prophase 1 of meiosis these pairs form a tetrad in a process called ______
2
How many daughter cells are created at the end of meiosis 1
4
How many daughter cells are created at the end of meiosis 2
homologous pairs
Matching chromosomes are called ______
true
True or false- one cell receives most of the cytoplasm during oogenesis
Interphase
Which phase of meiosis is this? - cells increase in size - two pairs of homologous chromosomes (paternal and maternal)
Interpahse
Which phase of meiosis is this? - centrioles/centrosomes duplicated - DNA replicates creating two copies of each chromosome
Telophase 1
Which phase of meiosis is this? - chromosomes at opposite sides of the cell - the nuclear membrane appears - cytoplasm pinches in forming a cleavage furrow - cytokinesis 1
Metaphase 2
Which phase of meiosis is this? - chromosomes join in the center of the cell - spindle fibers attach to the kinetochores
Anaphase 2
Which phase of meiosis is this? - chromosomes move to opposite sides of the cell - spindle fibers lengthen elongating the cell
Prophase 2
Which phase of meiosis is this? - chromosomes will tighten up if needed - nuclear membrane dissolves - spindle fibers form
Anaphase 1
Which phase of meiosis is this? - homologous pairs separate - spindle fibers length elongating the cell - random separation of homologous chromosomes resulting in an independent assortment creating genetic variation
Telophase 2
Which phase of meiosis is this? - nuclear membrane forms - spindle fibers disappear - cytoplasm pinches forming the cleavage furrow - cytokinesis 2
Prophase 1
Which phase of meiosis is this? - nuclear membranes dissolve, spindle fibers form, centrioles move toward the poles - a synapsis occurs when two homologous chromosomes come together - they line up and form a tetrad - paternal and maternal homologous exchange DNA (genes) which is called crossing over
Metaphase 1
Which phase of meiosis is this? - tetrad are pulled to the middle of the cell - spindle fibers form
zygote
a fertilized egg is called a ______
karyotype
a photograph of the chromosomes in a cell is called a ________
homologous chromosomes
chromosomes that are the same size, shape, and carry the same genes for the same traits are called _________
genetic recombination
during meiosis chromosomes will split into daughter cells randomly making each gamete unique. This is called ___________
4
each diploid cell divides by meiosis to form how many haploid cells spermatids
1
how many cells become fully mature during oogenesis
2
how many cycles of cell division are involved in Meiosis
gametes
sperm and egg cells are called _______
Oogenesis
the formation of eggs is through the process _______
Spermatogenesis
the formation of sperm is through the process _______
polar bodies
the other cells formed during oogenesis that don't fully form are called ______
autosomes
the remaining 44 chromosomes in humans are called ______
true
true or false- 4 cells develop heads and tails during spermatogenesis
a diploid
what is two complete sets of chromosomes called _______
sexual
what kind of cell division is meiosis (sexual or asexual)
crossing over
when homologous chromosomes exchange genes it is called _______
testes and ovaries
where do the gametes form
reproductive organs
where does meiosis occur
mitosis
which cell division results in diploid cells
meiosis
which cell division results in haploid cells
Anapahse 1 and Prophase 1
which phases can cause genetic recombination in meiosis
a haploid
what is one complete set of chromosomes called ______
