1. Genetic analysis of reciprocal differences in the inheritance of in vitro characters in pearl millet
Abstract Reciprocal differences persist in nature because of the unequal contribution of cytoplasmic determinants from male and female gametes to the zygote. The inheritance of genetic differences is an important factor that influences various traits, including somatic embryogenesis and regeneration in vitro. In this report, we estimate the cytoplasmic and m

2. Efeito de linhagem citoplasmática em características de produção de ovinos da raça Merino.
Objetivou-se avaliar a importancia dos efeitos de linhagem citoplasmatica sobre as caracteristicas peso corporal (PCORP), peso de velo sujo (PVS) e diametro da fibra da la (DIAM), respectivamente em 707 e 703 femeas e 350 machos da raca Merino com um ano de idade. Linhagens citoplasmaticas (LCT) foram definidas como as primeiras 41 femeas do pedigree registr

3. Effects of cytoplasmic inheritance on preweaning traits of Hereford cattle
The influence of cytoplasmic inheritance on birth and weaning weight was evaluated in an experimental Hereford herd. Data on 1,720 records for birth and weaning weights from calves born between 1963 and 2002 were studied. Variance components were estimated using MTDFREML procedures and an animal model was fitted for each trait. Direct and maternal additive e

4. Exclusion of male mitochondria and plastids during syngamy in barley as a basis for maternal inheritance
It is known from genetic analyses that maternal inheritance of cytoplasmic organelles is the rule among plants and animals. Although recognized as one of several possible mechanisms for strictly maternal cytoplasmic inheritance, exclusion of sperm cytoplasm at the time of gametic fusion has remained poorly documented for the flowering plants. In the present

5. Divergent Potentials for Cytoplasmic Inheritance within the Genus Syringa. A New Trait Associated with Speciogenesis1
Epifluorescence microscopic detection of organelle DNA in the mature generative cell is a rapid method for determining the potential for the mode of cytoplasmic inheritance. We used this method to examine 19 of the known 22 to 27 species in the genus Syringa. Organelle DNA was undetectable in seven species, all in the subgenus Syringa, but was detected in th

6. Genetics of Male Sterility in Gynodioecious Plantago Coronopus. I. Cytoplasmic Variation
Inheritance of male sterility was studied in the gynodioecious species Plantago coronopus using five plants and their descendants from an area of ~50 m(2) in each of six locations. The crosses were planned to test for cytoplasmic inheritance of male sterility. In four locations significant differences between reciprocal crosses were observed. The progenies o

7. Comparative Effects of Pollen and Seed Migration on the Cytonuclear Structure of Plant Populations. II. Paternal Cytoplasmic Inheritance
We continue our study of the effects of pollen and seed migration on the cytonuclear structure of mixed-mating plant populations by analyzing two deterministic continent-island models under the critical assumption of paternal cytoplasmic inheritance. The major results of this study that contrast with our previous conclusions based on maternal cytoplasmic inh

11. Uniparental inheritance of mitochondrial and chloroplast genes: mechanisms and evolution.
In nearly all eukaryotes, at least some individuals inherit mitochondrial and chloroplast genes from only one parent. There is no single mechanism of uniparental inheritance: organelle gene inheritance is blocked by a variety of mechanisms and at different stages of reproduction in different species. Frequent changes in the pattern of organelle gene inherita
