Meiosis Flashcards
process that contributes to genetic variety, doesnt make body cells
meiosis
it makes sperm and egg cells aka gametes
meiosis
sperm and egg cells have ___ chromosomes
23
where chromosomes condense and thicken, and are going to line up with their homologous pairs
prophase 1
chromosome are approximately the same size and the can contain the same types of gene in the same locations
homologous
where the chromosomes are lined uo in homologous pairs and they have a way to transfer their genetic info and exchange it between each other
crossing over
chromosomes lined up in the middle of the cell in pairs
metaphase 1
the chromosomes are going to be pulled away by the spindle fibers
anaohase 1
where you have two newly formed nuclei and meiosis 1 will end with 2 new cells and cytokinesis follows with splitting the cytoplasm
telophase 1
not eventful as it was in prophase 1
prophase 2
your chromosomes and spindles starting to form like in prophase 1
phrophase 2
the chromosomes are going to line up in the middle but theyre not in pairs anymore
metaphase 2
the chromatids are getting pulled away by the spindle fibers
anaphase 2
the nuclei reforms, the 2 cells are going to divide and 4 cells are going to be formed
telophase 2
when a cell can recieve too many or too few chromosomes in the separation
nondisjunction
