Chapter 11 Flashcards
what is common between mitosis and meiosis
they both divide the nucleus
what kind of cells does mitosis make?
body
what kind of cells does meiosis make?
sex cells
prophase in meiosis
chromosomes thicken, match with homologous pairs bind by tetrad & cross over
crossing over is means the chromosomes are now….
recombinant chromosomes
prophase in mitosis and prophase 2 in meiosis
nuclear membrane broken down, and chromosomes thicken and condense
metaphase in mitosis
chromosomes line up on the metaphase plate
anaphase in mitosis
chromosomes pulled away by spindles to opposite ends/poles
metaphase 1 in meiosis
chromosomes pair in the middle
anaphase 1
homolog chromosomes pulled to opposite sides of cell
prophase 2
chromosomes condense, membrane broken
metaphase 2
chromosomes line up on metaphase plate
anaphase 2
chromatids pulled away to opposite ends/poles
telophase 2
nuclei are forming to make 2 cells
cytokinesis (in telophase 2)
completely splits cytoplasm, ends w 4 identical gametes
sexual reproduction
1 gamete from each parent combines in fertilization
genetic diversity
mixing chromosomes from two individuals
gene
specific coding on chromosomes, to make traits
locus
gene’s specific location along chromosome
asexual reproduction
indiv. passes on gene without fusion
clone
genetically identical indv. from same parent
how many divisions does mitosis or meiosis have
mitosis:1 meiosis:2
where do homologs pair from in meiosis
tetrad
what type of body cells does mitosis make
clones
