Question
the accident (mistake) during meiosis that causes the membersof a homologous pair of chromosomes to fail to separate iscalled______________. This can produce an individual whose geneticmakeup is 2n+1 or 2n-1 (one too many or one too few chromosomes).the GENERA:L term for the genetic condition of having an abnormalnumber of chromosomes is called____________. the concept that pairs of genes separate during gameteformation became Mendels law of _________. This occurs during whatspecific phase of Meiosis ____________________. in meiosis, what are the two mechanisms that insure somedegree of genetic variability and when do they occur? the accident (mistake) during meiosis that causes the membersof a homologous pair of chromosomes to fail to separate iscalled______________.

the accident (mistake) duringmeiosis that causes the members of a homologous pair of chromosomesto fail to separate is called_NONDISJUNCTION_____________

This can produce an individual whosegenetic makeup is 2n+1 or 2n-1 (one too many or one too fewchromosomes). the GENERA:L term for the genetic condition of havingan abnormal number of chromosomes iscalled____________.ANEUPLOIDY

the concept that pairs of genesseparate during gamete formation became Mendels law ofSEGREGATION _
=======================================
. This occurs during whatspecific phase of Meiosis ____________________
ANAPHASE
.Segregation happens duringmeiosis I. That's when the homologous pairs of chromosomes synapseto form the tetrads. That means the homologous chromosomes line upside by side. They move to the equator of the spindle still pairedup. In anaphase I the paired chromosomes are separated from eachother, segregating the alleles.
Meiosis II is for getting the two sister chromatids of eachremaining chromosome pulled apart from each other.
===============================================
in meiosis, what are the twomechanisms that insure some degree of genetic variability and whendo they occur?
