New nuclear membrane formed around each group of 46 chromosomes When it goes
right, euploid cells are produced
Select the correct term
1Prophase 2Anaphase
3Telophase 4Metaphase
Don't know?
Interphase cell feeds, metabolizes and grows while replicating DNA in preparation for mitosis
Prophase first appearance of chromosomes (will be 92)
Metaphase Centrioles pull chromosomes to opposite sides of cell (chromatid) - 46 each side
Anaphase Centromeres split and sister chromatids are pulled apart
New nuclear membrane formed around each group of 46 chromosomes When it
Telophase
goes right, euploid cells are produced
Nondisjunction Error in meiosis in which homologous chromosomes fail to separate.
Polyploidy condition in which an organism has extra sets of chromosomes
Triploidy when an organism has three copies of every chromsome instead of two
Tetrapoloidy euploid has 92 chromosomes and fetus usually does not survive
Single gene disorder (trinucleotide repeat
mutation) Autosomal dominant (50% chance of
Huntington's disease
passing it on) Progressive neurologic disease with
late onset (40s) Prevention- genetic testing for
pregnancy planning
Single gene disorder (CFTR gene mutation)
Autosomal recessive
Most common in white children
Cystic fibrosis
Defective transport of chloride ions cause salt imbalance- thickened secretions,
digestive issues, malnutrition. Males and females
Must inherit two copies of gene (1 from each parent)
XO chromosomal disorder, monosomy of X-affects females
