Abstract 59 SUlOIARY In this study the lip prints were collected from thirty Egy,tian families from ~onofia Governorate. These families were composed of ODe hundred aod thirty nine members, sixty parents, forty six male and thirty three female offspring. The lip prints were collected by two methods, lip stick method and coloured photographio method. It was found that the commOD pattern types of lip prints among the members of these families were found to be the pattern type IV,III,lIb and Is. Pattern type IV and III were observed on all six topographical areas of the lips and the pattern type IV was the commonest type. Pattern type lIb was greatly seen on area A aod B although it was seen on other areas. Also, pattern type Ia was only seen on two aress B snd E but more commoo in area E. The rare pattern types of lip prints were pattern types Ib,IIa aod V. Combinations of the different paternal phenotypes in all topographical areas of the lips were recorded io all families Bnd the types of lip patterns which transmitted to their offsprings were stUdied, and the mode of inheritance of each type was concluded. CONCLUSION lrom this study, these data were conoluded 1) The pattern type IV of lip prints is transmitted by a dominant gene OD all the six topographical areas of the lip. 2) The pattern type lIb is transmitted by a dominant gene on all of the topographical areas on whioh it appeared. J) The pattern type la is transmitted by 8 dominant gene on both areas Band E where it appeared. 4) The pattern type lb’ lIb and III are transmitted by reoessive genes. 5) The pattern type V of lip prints is transmitted by a rare recessive gene. |
