mortality/aging
• 79% of mice with proximal Chr7 paternal duplication survived birth; 89% of normal siblings survived birth
• maternal duplication of distal Chr7, 7E2 to the telomere, results in mid-gestation lethality
• mice with paternal duplication of distal Chr7, 7E2 to the telomere, die during early embryonic development

reproductive system
• both maternal or paternal duplication of Chr7 segments result from heterozygous matings

cellular
• both maternal or paternal duplication of Chr7 segments result from heterozygous matings
• some offspring produced by intercrossing heterozygotes inherit 2 maternal copies of proximal Chr7, breakpoint 7E2 to the centromere, containing imprinted genes
• some offspring produced by intercrossing heterozygotes inherit 2 maternal copies of distal Chr7, breakpoint 7E2 to the telomere, containing imprinted genes
• 5.3% of offspring produced by intercrossing heterozygotes inherit 2 paternal copies of proximal Chr7, breakpoint 7E2 to the centromere, containing imprinted genes
• intercrossing heterozygotes also produces offspring that inherit 2 paternal copies of distal Chr7, breakpoint 7E2 to the telomere, containing imprinted genes

growth/size/body
• observerd in chimeras comprising cells with paternal duplication of distal Chr7, 7E2 to the telomere, and wild-type cells
• mice with paternal duplication of proximal Chr7 show slower growth from birth to weaning age

limbs/digits/tail

reproductive system
• Background Sensitivity: mean sperm counts for heterozygous males are significantly lower than for wild-type males; substituting CBA/H for C57BL/6J in the background normalizes the sperm count
• lowered sperm count is not signficant enough to be the reason for decreased fertility
• lowered sperm count is associated with reduction in testis weight
• Background Sensitivity: frequency of sperm-head abnormalities is doubled compared to wild-type; difference was significant only in presence of CBA/H alleles
• Background Sensitivity: decreased frequency of ring configurations are seen, compared to mice inheriting strain CBA/H alleles
• resolve to chromosomally unbalanced gametes and reduced fertility
• mean testis weights were significantly reduced compared to wild-type males
• lowered weight is associated with decreased sperm count

endocrine/exocrine glands
• mean testis weights were significantly reduced compared to wild-type males
• lowered weight is associated with decreased sperm count

growth/size/body
• body-weights are slightly reduced in translocation carriers compared to wild-type siblings
