meosis Flashcards
where does meosis ocour
gametes
what type od cells are gametes
haploid
what does a haploid cell mean
only one copy of each chromosome
does miosis take place in haploid or diploid cells
diploid
what is the first stage in meiosis
repliaction of dna in each chromosome producing two chromatids
what is the second stage of meiosis
where the dna condenses to form chromosmes
what forms these chromosmes
two chromatids joined at the centromere
what is the third satge in miosis
the first division the chtomosomes arrange themselves into homologous pairs along the equator and are pulled appart by the spindle fibres
what does this first division create
two cells with a halved chromosome number
what is the fourth step in mieosis
second division - pairs of sister chromotids that make up each chromosome are seperated - the centromere is divided
what does this second division produce
four haploid daughter cells wich are genetically different
