1 Chapter 46 and 47

2 Asexual Reproduction Fission Fragmentation and regeneration Budding Parthenogenesis

3 Sexual Reproduction Hermaphroditism – continual Hermaphroditism - sequential

4 Animal Reproduction, continued Fertilization: internal vs. external Environmental vs. courtship Oviparous vs. viviparous Monotreme, marsupial, & eutherian mammals Role of pheromones

7 The Female Reproductive System

8 Oogenesis Controlled by gonadotrophic hormones: FSH LH Estrogen Progesterone

9 Types of Ovulation Reflexogenic Ovulators Periodic Ovulators Short Periodic Ovulators

10 Male Reproductive System

11 Spermatogenesis In seminiferous tubules FSH stimulates Sertoli cells LH stimulates Leydig cells

13 Fertilization (Fallopian Tubes)

14 Blocks to Polyspermy Fast block – Change in polarization Slow block – Signal transduction pathway

15 The Gray Crescent

16 Cleavage - Morula

17 Blastula Inner mass = future embryo Trophoblast = future placenta, secretes HCG
