what is dominant during the follicular phase?
follicle
what is dominant during the luteal phase?
CL
what is it called when the female is sexually receptive to a male for copulation?
estrus
what is it called when immediately following ovulation the CL is forming?
metestrus
what is it called when the CL is producing peak progesterone, and is the longest amount of time?
diestrus
what is it called when the dominant follicle is producing lots of estrogen and the CL is regressing?
proestrus

diestrus
when is the corpus albicans dominant?
proestrus
what is the follicular wave theory?
follicles develop in coordinated groups
