meiosis

During prophase 1 what are the chromosomes doing

condense and match up with their homologous pairs

what does homologous pair mean

the chromosomes are about the same size and contain same types of genes in the same location

homologues pair consist of what

one from mom and one from dad

the exchange of genetic information between homologues pairs during prophase 1 is called what

crossing over

crossing over of homologues chromosomes results in what

recombinant chromosomes

in metaphase 1 the chromosomes line up in the middle of the cell in pairs called what

tetrads

anaphase 1 in meiosis is the pulling apart of what to the opposite sides of the cells

chromosomes 

after the end of meiosis 1 what is the product

2 haploid daughter cells

how many chromosomes do the haploid cells contain after meiosis 1

23 chromomsomes

metaphase 2 how are the chromosomes lined up

in the middle single file lined like mitosis

anaphase 2 

chromosomes are pulled apart by the chromatids 

end product of meiosis produces

4 non-identical cells called gametes (sperm and eggs cells)

gametes are haploid what does this mean

they contain half the amount of chromosomes that the original parents cell contains

an example of a cell that is 2n is a

somatic cell

what is a somatic cell

other cells outside the reproductive cells (gametes)

tetrads are refferd to as what

two pairs of homologous chromosomes or four chromatids

recombinant chromosomes

created when crossing over combines DNA from two parents into a single chromosomes
