Historic and total protein content permanently increased during the reduction and in the formation of tetrads and pollen grains. In the process of the reduction division, deoxyribonucleic acid (DMA) is synthesised in greater quantities than in the later stages of tetrad formation. However, even greater synthesis of DNA occurred during pollen formation than in the cells during reduction division and 'tetrad formation. These differences were large and depended on pollen shape. Synthesis of ribonucleic acids (RNA) during the reduction division, tetrad and pollen formation was variable and in negative correlation with the DNA content.

The genetics of rust reaction to race 297 of flax rust (Melampsora lini) was studied in the F1, F2, F3 and back-cross generations of the crosses DeOro x B-5128 and DeOro x Windom. The segregation of rust reaction indicated one gene difference between the parents. The N1 gene was segregating in the F2, F3 and back-cross generations of the two crosses, with DeOro having the double recessive alleles. Resistance was dominant to susceptibility. Rust reaction was inherited independently from seed and flower colors.

Abstract
Omran, A. O. (1973): Inheritance of seed and flower colors in flax. Genetika, Vol. 5, No. 3, 281-285.
The inheritance of seed and flower colors was studied in the F1, F2 and F3 generations of four crosses between the yellow-seeded variety DeOro and four brown - seeded varieties: Dillman, Linore, B-5128 and Vindom. Seed color and flower color were perfectly associated in this study. All the blue-flowered plants had brown seed and all pinkish-white-flowered plants had yellow seed. Blue flowers and brown seeds were dominant to pink flowers and yellow seed. One gene difference between any two parents appeared to be governing flower color with a probable pleiotropic effect for seed color. Rust reaction was inherited independently from seed and flower colors.

This investigation has been carried out in order to determine the effect of temperature on reciprocal and non-reciprocal recombination between Neurospora crassa arg-3 mutants which were kindly supplied by Professor Catcheside.
The results obtained showed that both reciprocal and non--reciprocal recombination between the arg-3 mutants in pairs were affected by temperature. The temperature effects on both types of recombination were inconsistent in crosses between strains of the mutants of different origin.

Due to an increased demand for vegetable oil in recent years and the high quality of corn oil, an extensive breeding programme to increase the content and improve the quality of oil in corn has been initiated.
A number of inbred lines from the above programme with oil contents ranging from 3.21 to 12.51 percent, which had previously been screened for other agronomically important traits, was studied in respect to: (a) variation of oil content in single kernels, (b) variation of fatty acid composition of the oil, and (c) relationship of oil content to fatty acid composition as well as the relationship among the major fatty acids. The results are discussed with regard to the relationship of oil content and quality, and the breeding potential of the investigated lines.

In this report the status of the patient, development of the disease and laboratory examinations with cytogenetic analysis were described for a female newborn, with congenital lymphoblastic leukemia and Down's syndrome. The infant died 10 hours after birth. The postmortem examination confirmed the presence of leukemia foci in the liver, lungs, spleen thymus and pancreas. According to reports in the medical literature, the association of congenital leukemia with Down's syndrome in the neonatal period is rare, therefore the authors consider that these findings might be of interest.

A cytogenetical examination of a family which is a carrier of a deletion of the shorter arm of one of the G group chromosomes (Christchurch chromosome) is shown. One of the carriers had several spontaneous abortions. A more precise determination of this aberrant chromosome was done using an autoradiographic method and a banding technique.

Hybrid female Lewis x Hooded rats, with morphologically distinguishable X chromosomes were used for cytogenetical verification of the hypothesis (Lyon, 1961) concerning the activation and inactivation of the X chromosome in mammalian female complements and late and early replication of X chromosomes.
Autoradiographic detection of late replicators in an in vitro culture of cells, showed non-random distribution of late replication of the X chromosome, in these hybrid females.

This paper summarizes the current state of chromosome studies in patients with malignant haematalogical disorders. Emphasis has been placed on the significant cytogenetical data so far provided which contribute to the understanding of the mechanism of malignant growth of haematopoietic tissue.
The conclusion derived is that the role of chromosome abnormalities in the causation and course of human malignant haematological disorders 'remain controversial.

The authors have noticed an increase in the number of children with congenital anomalies at the Children's Clinic in Belgrade. The results of follow-up for a number of years are given. In a search for the reason for these anomalies, are examined during a five year period 106 patients with multiple anomalies and psychomotor retardation. In this group of children, 14.1% had chromosome aberrations, particularly trisomy of the G chromosome, but the number of children with aberrations of sex chromosomes was also great.

Abstract
Ševaljević, Lj. (1973): Some properties of sea urchin deoxyribonucleic acids and the amino acid composition of residual proteins completed with them, - Genetika, Vol. 5, No. 3, 351-358.
The DNAs were prepared from sea urchin eggs and embryos by two different methods and the amino acid composition of the protein complexed with them was estimated. Egg and zygote DNAs prepared by a phenol method were found to be degraded, while gastrula DNA was more resistant to such degradation. Using a CsCl method high-molecular-weight cytoplasmic and nuclear DNAs were obtained which differed in buoyant density, and in the amount and composition of the protein complexed with them.

Abstract
Djordjević, B., Perez, A. G. and Hopfan, J. (1973): Radiation response of chronically hypoxic HeLa cells. - Genetika, Vol. 5, No. 3, 359-365.
Assay HeLa cells were rendered hypoxic by co-incubation with an excess of non-proliferating but metabolically active; »fee-der« cells. Such dense cultures exhibited much higher survival under gamma irradiation than did cultures incubated with metabolically inactive feeder cells. Hypoxia, as indicated by increased survival after gamma irradiation remained high over a 20 hour period. It is suggested this system may be used with chronically irradiated mitotically synchronized cells.
