Animal Reproduction and Gametogenesis

Flashcards covering key vocabulary terms related to animal reproduction and gametogenesis, tailored for study and review.

Live Birth

A reproductive method where offspring are born alive, as seen in most mammals.

Gonochoristic

Referring to species with separate sexes, where individuals are either male or female.

Hermaphroditic

Species that have both male and female reproductive organs within the same individual.

Oogenesis

Parthenogenesis

A form of asexual reproduction where an egg develops into an organism without fertilization.

Fission

Fragmentation

A form of asexual reproduction involving the breaking of an organism into parts, each of which can develop into a complete individual.

Corpus Luteum

A temporary endocrine structure involved in the menstrual cycle and early pregnancy that produces hormones such as progesterone.

Menstrual Flow Phase

The phase of the uterine cycle that involves the shedding of the uterine lining when pregnancy does not occur.

Ambiguous Pharmacological Control

The control exerted by hormones from multiple glands regulating reproductive processes.

Embryo

Blastocyst
