meiosis Flashcards
during meiosis the chromosome number is
reduced
prophase 1 of meiosis and mitosis
different
anaphase 1 centromeres
do not divide
oogenesis
one ovum
crossing over
prophase 1
crossing over
an exchange of information between two homologous chromosomes
type of cell that undergoes meiosis
germ cell
what is synapsis and when does it occur
where homologous pairs meet up to make tetrads (crossing over) prophase 1
what is a tetrad
two chromosomes that form a homologous pair
how are genes aligned on homologous chromosomes
samely
what happens during crossing over
The chiasmata Exchange genetic material
type of genetic material exchanged during crossing over
gene
what is independent assortment
the random alignment of homologous pairs and separation during anaphase 1 which leads to genetic diversity
