查询词典 reproductive

According to the results, we can find that female reproductive systemis made up of ovary, lateral oviduct, common oviduct, spermatotheca, accessory glandand genital chamber, which is typical polytrophic type. Then the male reproductivesystem consists of testes, vas deferens, vas efferens, seminal vesicle, ejaculatory duct,male accessory gland and pygostyle. Moreover accessory gland is fully developed,seminal vesicle is unclear, males testes and testicular follicle has degenerated before itflying, and the quantity of testicular follicle is different from the other kind of ants.

从生物学、生理学的角度，在讲述这门课开设的意义、性分化的生物学意义和人类生殖模式的基础上，简要讲述人类性行为的特点和进化，进而讲解男女生殖器官的基本结构与机能、性机能的生物学和生理学基础及其调节控制、人类受精、胚胎发育、生育、性的发育与分化以及青春期的生物学、生理学知识和问题，并讲述人类遗传病、性卫生、性传播疾病包括艾滋病的预防和控制等基本知识。

Reproduction is a key process, which highly influences the economic efficiency of pig production. Traditional quantitative genetics plays a very important role in animal breeding. Selection for increased number of piglets born has been employed in pigs with only limited success because of the low heritability, the late expression in life and the sex-limited nature of reproductive traits.
