25. Patterns of Mating and Mitochondrial DNA Inheritance in the Agaric Basidiomycete Coprinus Cinereus
Patterns of mating and mitochondrial DNA (mtDNA) inheritance were investigated for the Basidiomycete, Coprinus cinereus in order to better understand the relationship of reproductive biology and mtDNA evolution in fungi. Results showed that the unique mating system of basidiomycetes can lead to the formation of mitochondrial mosaics (i.e., colonies composed

26. Consistency of genetic inheritance mode and heritability patterns of triglyceride vs. high density lipoprotein cholesterol ratio in two Taiwanese family samples

27. Pseudohypoparathyroidism: inheritance of deficient receptor-cyclase coupling activity.
Pseudohypoparathyroidism, type I (PHP-I) is an inherited disorder of primary resistance to multiple hormones that work by stimulating adenylate cyclase. In an attempt to clarify the mode of inheritance of PHP-I, we measured the activity of the N protein, a receptor-cyclase coupling component, in erythrocyte membranes. Erythrocyte N-protein activity was reduc

28. Simultaneous inheritance and expression of classical haemophilia A and type IIA von Willebrand's disease.
A family is described in which the mother is a haemophilia carrier, the father has asymptomatic type IIA von Willebrand's disease, and their second son has simultaneously inherited both severe haemophilia and type IIA von Willebrand's disease. This is the first report of both diseases occurring simultaneously. The inheritance patterns and laboratory data on

29. Structural polymorphism of the fourth component of human complement
The fourth component of human complement (C4) in 102 individual plasma samples has been examined by the technique of antigen-antibody crossed electrophoresis (AACE). Electrophoretic heterogeneity of C4 was manifested by the repeated occurrence of seven different precipitin patterns. These patterns were formed by varying combinations of three subtypes of C4,

30. Counselling dilemmas associated with the molecular characterisation of two Angelman syndrome families.
We report the molecular characterisation of two families with Angelman syndrome referred for prenatal diagnosis, in which atypical molecular findings resulted in counselling dilemmas. The first is a familial case of Angelman syndrome in which the two affected children have mutations which affect the imprinting mechanism, as shown by the presence of paternal

31. Peripheral absolute threshold spectral sensitivity in retinitis pigmentosa.
Dark-adapted spectral sensitivities were measured in the peripheral retinas of 38 patients diagnosed as having typical retinitis pigmentosa (RP) and in 3 normal volunteers. The patients included those having autosomal dominant and autosomal recessive inheritance patterns. Results were analysed by comparisons with the CIE standard scotopic spectral visibility

32. No actual conflict over colony inheritance despite high potential conflict in the social wasp Polistes dominulus
Social insect societies are outstanding examples of cooperation and conflict. Individuals work together, yet seek to increase their inclusive fitness at each others' expense. One such conflict is over colony inheritance, when a queen inherits the colony following the death of the previous queen. Colony inheritance is common in the social wasp Polistes dominu

33. Fetal and maternal contributions to risk of pre-eclampsia: population based study
Objective: To use familial patterns of recurrence of pre-eclampsia to investigate whether paternal genes expressed in the fetus contribute to the mother’s risk of pre-eclampsia and whether mother’s susceptibility to pre-eclampsia is related to maternal inheritance by mitochondrial DNA.

34. Differential methylation of chloroplast DNA regulates maternal inheritance in a methylated mutant of Chlamydomonas
In Chlamydomonas, the maternal inheritance of chloroplast genes correlates with the differential methylation of chloroplast DNA (chlDNA) in females (mt+) but not in males (mt-). Our previous studies have supported our methylation-restriction model in which the maternal transmission is accounted for by the differential methylation in gametes which protects fe

35. Complex patterns of inheritance of an imprinted murine transgene suggest incomplete germline erasure
Here we report a transgenic mouse line that exhibits significant deviations from a classic pattern of parental imprinting. When the transgene is passed through the female germline, it is completely silenced in some offspring while in others expression is reduced. This variable expressivity does not appear to be the result of differences in the presence of un

36. cis-Acting Signal for Inheritance of Imprinted DNA Methylation Patterns in the Preimplantation Mouse Embryo
The inheritance of gametic methylation patterns is a critical event in the imprinting of genes. In the case of the imprinted RSVIgmyc transgene, the methylation pattern in the unfertilized egg is maintained by the early mouse embryo, whereas the sperm’s methylation pattern is lost in the early embryo. To investigate the cis-acting requirements for this pre
