| 1. | In many organisms the male and female gametes are different . 很多生物体中雄配子与雌配子是不同的。 |
| 2. | Study on 2n female gamete induction and triploid diversity of lilium oriental 雌配子诱导及三倍体多样性研究 |
| 3. | It is a multicultural flask - shaped structure made up of a narrow neck and a swollen base ( venter ) that contains the female gamete 颈卵器状似长颈烧瓶,由一条细长的颈部和膨大的腹部(内含雌性配子)组成。 |
| 4. | Characters controlled by the dna of extranuclear organelles are not inherited according to mendelian laws and are transmitted only through the female line , since only the female gametes have an appreciable amount of cytoplasm 由于细胞质大多来自母体所产生的配子,所以由细胞核外的细胞器的dna所控制的遗传性状一般只随母系而遗传,也不符合孟德尔定律。 |
| 5. | The gametophyte ( pollen grain ) contains all the genetic information required to unite with the female gamete at fertilization and to form a new sporephyte . a relatively large number of genes are required to program pollen development 在高等植物中,花的发育是一个复杂的过程,涉及到由营养分生组织(或花序分生组织)向花分生组织的转变,花的形态建成以及雌、雄配子体的发育和分化。 |
