2 genetically identical diploid cells
4 genetically different haploid cells
process in sexual reproduction in which male and female reproductive cells join to form a new cell
a threadlike body in the cell nucleus that carries the genes in a linear order
one of two identical sister parts of a duplicated chromosome
the area where the chromatids of a chromosome are attached
chromosomes that each have a corresponging chromosome from the opposite-sex parent.
specialized cell involved in sexual reproduction
male gamete (haploid, N)
female gemete (diploid, 2N)
a cell that contains only a single set of chromosomes and therefore only a single set of genes.
a cell that contains 2 copies of each chromosome
the structure that pulls apart the chromosomes during mitosis
anchors that pull chromosomes apart
a cell containing 4 chromatids that formed during meiosis
growth , replicating of dna, and preparation for mitosis
1st part of mitosis, chromosomes condense in the middle
2nd, chromosomes line up along the middle (x's)
3rd, in amazing synchronization, chromosomes pull apart
4th and final stage of mitosis, this is when the chromosomes gather at the poles
animal cell: cells pull apart. Plane cell: new cell wall grows
like cartilage for human bones, it is the start of a new cell wall for plants.
when homologous chromosomes swap dna while in tetrads
the farther apart genes are on chromosome, the more likely they are to be seperated by a crossover in meiosis
use recombination rates to MAKE gene map
