Trisomy 21 (nondisjunction) Down syndrome is usually caused by an error in cell division called nondisjunction.. Nondisjunction results in an embryo with three copies of chromosome 21 instead of the usual two. Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate.
This can be said with any meat purchase. While a rack of lamb or a decent chop might cost you between $12 to $15 per pound, one can easily buy lamb ribs for under $5.

Ribs retail for as little as $4.50 per pound, while the loin and sirloin chops retail for $12 per pound.
