- parthenogenesis

Students have asked these similar questions
Where does fertilization (the union of a sperm and egg) take place?
vagina
uterus
ovary
oviduct
zygote
epididymis
Parthenogenesis
only occurs in Animals with
separate sexes that produce egg and sperm, but
how is it exactly like asexual reproduction? Choose
all that apply.
O Production of offspring does not involve the fusion of
gametes
Only one individual contributes genetic material to the
offspring
Gametes are produced by opposite sexes
Fertilization is required for offspring to develop
Gametogenic cells always complete meiosis to
produce haploid gametes
How are these systems different?

- Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.arrow_forwardBesides producing gametes (sperm and eggs), the primary male and female reproductive organs also produce sex hormones. The _____ and the pituitary gland control secretion of both.arrow_forwardPart A Which of the following processes results in the offspring of sexual reproduction being genetically different from their parents? cytokinesis protein synthesis mitosis O fertilization Submit Request Answerarrow_forward

Key processes in sexual reproduction are meiosis and fertilization. This process involves the production of sex cells or gametes. The union of two gametes resulting into a zygote is called fertilization.arrow_forwardIn cats, each cell normally contains 19 pairs of chromosomes (2n=38).
