Table 2. The frequency of aneuploidy in oocytes from young donors versus oocytes from aged donors.

Experimental group	Total number of oocytes analyzed by CGH	Total number of oocytes with aneuploidy	Frequency of aneuploidy (%)
Miniature pigs young	33	4	12.1
Miniature pigs old	46	4	8.7
LxCLW old	59	6	10.2

Table summarizing the frequency of aneuploidy in oocytes isolated from various age categories. The total number of oocytes analyzed by comparative genomic hybridization (CGH) together with the number of oocytes with incorrect chromosomal counts and their frequency per group is indicated. LxCLW stands for crossbred of Landrace and Czech Large White pigs.
