| germ line transformation | Micro injection of foreign DNA into an early embryo, so that it becomes incorporated into the germ line of the individual and thus stably inherited in subsequent generations of transgenic organisms. Typically, the DNA would be a reporter gene or cDNA in a vector such as a transposon, that might also carry a visible marker gene such as eye or coat colour), so that successful transformation could readily be detected.

| pectineal line | A ridge running down the posterior surface of the shaft of the femur from the lesser trochanter to which the pectineus muscle attaches; continuous superiorly with intertrochanteric line and inferiorly with the medial lip of the linea aspera. Synonym: linea pectinea. (05 Mar 2000) |
