In order to explore the differentially expressed genes in early embryo between male and female of silkworm, in this experiment,the early embryos of silkworm parthenogenesis eggs were prepared by Ameiotic Parthenogenesis ( AMP ) and Bispermic Androgenesis ( BSA ) technology and the forward and reverse direction subtracted hybridization cDNA libraries between female a
主要研究结论如下:1、家蚕单性生殖卵的制备以菁松×皓月品种家蚕为材料,利用非减数分裂孤雌生殖(AMP)和双精雄核发育(BSA)单性生殖技术,分别获得家蚕单一雌性和雄性早期胚胎发育蚕卵。

Reproduction without meiosis or formation of gametes.
无配生殖，无融合生殖无须减数分裂或形成配子的繁殖
Meiosis, which usually precedes spore or, sometimes, gamete formation, halves the chromosome number to produce haploid gametes.
染色体数目减半通常发生在减数分裂产生孢子或往往是合子减数分裂形成单倍体配子时。
Meiosis, which occurs only in the formation of gametes, is a specialized form of cell division.
仅仅发生在配子形成中的减数分裂是一种特殊形式的有丝分裂。
Such a gamete may be produced by tetraploid tissues, or it may be the result of faulty meiosis.
这样的配子可能是通过四倍体组织或者是错误的减数分裂产生的。
The processes by which gametes are formed, including the reduction of chromosomes in a germ cell from the diploid number to the haploid number by meiosis.
结合的过程配子形成过程，包括生殖细胞因成熟分裂造成其内铬酸由二倍体数减少到单倍体数的过程
Generally meiosis occurs before gamete formation, resulting in the gametes being haploid (having half the normal number of chromosomes).
在配子形成前通常会发生减数分裂，产生单倍体的配子（染色体数为正常的一半）。
The gametophyte is derived from the product of a reduction division in the megaspore mother cell.

Gametes may develop without fertilization, or meiosis may substantially precede gamete formation.
配子不经过受精也可能发育，若减数分裂先于配子形成，配子也可能发育。
