(Exam 2). Biology 123 Lab. Meiosis
What is meiosis I? - answer separation of homologous chromosomes
What is meiosis II? - answer separation of sister chromatids
During meiosis I, what happens with the sister chromatids? - answer They stay together
What occurs during interphase before meiosis? - answer copies being made of each
chromosome
In interphase, what do the homologous chromosomes do? - answer pair together at
synaptonemal complex
When does crossing over occur? - answer Prophase 1 in meiosis I
Where is the crossover site? - answer chiasma
What happens in prophase I? - answer crossing over
What happens in metaphase I? - answerPaired homologous chromosomes line up
What happens in anaphase I? - answerHomologous chromosomes separate
What happens in telophase I + cytokinesis? - answerA nuclear membrane forms around
each cluster of chromosomes, split
What type of cells does meiosis I start and end with? - answer1 diploid turns into 2
haploids
Meiosis II is very similar to what? - answermitosis
What type of cells does meiosis II start and end with? - answer2 haploids turn into 4
