3 Flashcards
meiosis
process by nuclear division that REDUCES the number of chromosomes in new cell to HALF the # in the original cell
gamete
a haploid cell that fuses w/ another haploid cell to become a zygote
crossing over
exchange of corresponding segments of DNA
independent assessment
random separation of the homologous chromosomes occurs in anaphase
gametes
haploid reproductive cells. (sperm eggs)
spermatogenesis
production of sperm cells
polar bodies
the haploid offspring cell that die off
during synapsis the chromosomes
like up next to their homologous
during crossing over proteins of Chromatids break off and
attach to adjacent chromatids on the homologous
chromosome
Which phase of meiosis do tetrads form
prophase 1
meiosis 2 separates chromatids into
opposite poles of the cell
In oogenesis a diploid reproductive cell divides meiotically to produce
one haploid gamete
