| Heterotrophic organisms must acquire nutrients to maintain somatic and gametic function. |
|
| Several gametic and zygotic reproductive barriers were found in a cross between Japonica and Indica rice varieties. |
|
| The two gametic nuclei in each cell unite, thus restoring the diploid number of chromosomes. |
|
| A bridge of cytoplasm forms between the two ciliates, and one gametic nucleus from each cell passes into the other cell. |
|
| If that is achieved, those cells will undergo meiosis and provide a normal gametic contribution to the next generation. |
|
| The main objective of the action is to discover the biological controls of gametic embryogenesis and to exploit these in plant breeding. |
|
| These observations demonstrate that a mechanism contributed by the cytoplasm of the wild-type gametic cell recognizes abnormal-length flagella and restores length control. |
|
| Simultaneous analysis of the haploid megagametophyte and diploid embryo in a seed allows the female and male gametic contributions to the zygote to be separated. |
|
| Indeed, usually the marker phenotypes do not provide the gametic phase of the chromosomes, for example, in the case of a double or multiple heterozygote. |
|
| The process involves the fusion of gametic nuclei rather than independent gamete cells. |
|
| But, because only one individual is involved, there is no exchange of gametic nuclei. |
|
| Infections occurred principally in the visceral connective tissues of the digestive gland and the gonad, destroying gametic tissue and often causing host sterilization. |
|
| First, when farmed geoducks are in proximity to wild geoduck aggregations, spawning may be synchronized, with subsequent gametic interaction occurring. |
