Speci c transcript) becomes active only on the chromosome that will become the barr body. Connected, the genes are genetically unlinked; alleles of such genes assort independently, as if they were on different chromosomes: cytogenetic maps- locate genes with respect to chromosomal features (ex stained bands that can be seen in the microscope) Bio 191 slightly taller than average, but they are at risk for learning disabilities but are fertile: turner syndrome (monosomy x)- occurs about once in every 2500 female births and is only known viable monosomy in humans.
