however , our isolation in the monosomic strain of multiple , independent alleles of just three genes suggests that only a small proportion of the genes on chromosome i is easily mutable to give a ts -- lethal phenotype. -- during these studies , we located cdc24 on chromosome i and determined that it is centromere distal to pyk1 on the left arm of the chromosome .
