Flashcards in Meiosis Deck (14)
meiosis has ___ DNA replication followed by ___ cell divisions
can meiosis occur in haploid cells?
no, it requires a diploid cell with pairs of homologs
the end result of meiosis is
to make haploid cells for the haploid stage
meiosis I stages
prophase I, metaphase I, anaphase I, telophase I
meiosis II stages
prophase II, metaphase II, anaphase II, telophase II
meiosis I separates ____ and meiosis II separates ___
homologs, sister chromatids
homolog behavior in meiosis I
pair up parallel to each other with gene loci matching
form a physical unit called a bivalent/tetrad
one bivalent consists of ___ homologs, or 4 ____
the zipping-up of a pair of homologs
after homologs undergo synapsis they...
recombine with each other
the homologs then separate and 2 daughter cells are formed
after meiosis I, the two daughter cells are already considered to be ___
after meiosis II the daughter cells are still considered....
what phase takes up most of the time in meiosis?
prophase I of meiosis I
