| 1. | An isolated cell comes close to satisfying the likeness of a zygote .
一个分离的细胞接近达到合子的外貌。 |
| 2. | The zygote has a fixed complement of genetic information in its nucleus .
合子的核中具有固定的全部遗传信息。 |
| 3. | The classical literature of embryology documents these patterns in detail for the zygote .
胚胎学的经典文献详细地报道了合子的这些式样。 |
| 4. | This is the heterozygous form
这是杂合子的情况。 |
| 5. | Sickle cell anemia represents patients who are homozygous for hemoglobin s ( i . e . hemoglobin ss )
镰状细胞性贫血是指血红蛋白s为纯合子的患者（如血红蛋白ss ） 。 |
| 6. | Alternatively , like allopolyploids , they may arise by the nondisjunction of chromatids during the mitotic division of a zygote
与异源多倍体相似的是，它们也是在有丝分裂中合子的染色单体不分离形成的。 |
| 7. | Haplont a haploid organism that represents the vegetative stage in life cycles in which diploidy is restricted to the zygote
单倍性生物：是一个单倍体或生物体，该生物体体现二倍性仅限于合子的生活史中的营养阶段。 |
| 8. | Karyogamy the fusion of two nuclei that exist within a common cytoplasm , as occurs in the formation of the zygote from two gametes
核配：同一个细胞中两个核之间的融合现象称为核配，核配发生在两个配子结合成合子的过程中。 |
| 9. | Usually the more unlike the parents are the more hybrid vigor is released , but the effect diminishes in subsequent generations as more recessive homozygotes reappear
通常，亲本越不相似，产生的杂种优势越强，但这种优势使下一代的隐性纯合子的出现机率更多。 |
| 10. | In this species , the first division of zygote produces two equal hemispheric cells by the first partition wall at the right angles to the axis of the archegonium
合子的第一次分裂面垂直于颈卵器的长轴，产生两个相等的子细胞，靠近颈卵器颈部的营养器官原始细胞和远离颈部的基足原始细胞。 |
