What else can I help you with?
Do fish have menstruation?
No, fish do not menstruate; menstruation and the related estrus is particular to mammals. Roughly equivalent to menstruation in fish is the breeding seasons that fish go through at particular times of the year.
Which term describes something that happens in female mammals?
X chromosome inactivation happens in female mammals.
What do all mammals go through?
All mammals go through a starting stage as a single cell. They all go through cell division, birth, and growth. Not all mammals have periods (e.g. cats do not have bleeding periods.) All mammals die.
Do dogs go through menopause if so When?
No, menopause is a primate-only event in which menstrual cycles become erratic and then cease. As dogs do not have menstrual cycles, they do not go through menopause. Dogs have estrus cycles, and under certain conditions can go through a period of anestrus when they stop having estrus cycles. Late in life, a female dog may permanently go into anestrus, but this is not all that common.
What hormone is responsible for the occurrence of estrus?
Estrogen is the hormone responsible for the occurrence of estrus in female mammals. It helps regulate the reproductive cycle and brings about the physical and behavioral changes associated with being in heat.
Do mares still go into estrus when infertile?
If the mare is infertile because of age, yes they will continue to go into estrus. The hormones still work, but no more eggs are being released. If the mare has been spayed (which is very rare) and the ovaries are removed, the mare will no longer go into estrus.
How long do mice ovulate?
Mice are in estrus for a period of about 10 to 12 hours, and they will go into estrus every 3 or 4 days.
How long does it take a rabbit to get estrus?
Rabbits do not have a typical estrus cycle as other mammals. Rabbits are stimulated to ovulate by the mating act, and as such, can be ready to mate and conceive again as soon as they drop each litter -- approximately every 30 days.
Can rabbits have pierods?
Rabbits do not have menstrual periods like humans. Instead, female rabbits go through a reproductive cycle called estrus, during which they can become receptive to mating. This cycle typically occurs every 4 to 5 days, and if not bred, they do not experience bleeding or shedding of the uterine lining as mammals with menstrual cycles do.
Do cats go through menopause?
No. Menopause is the period when women stop menstruating, and since cats do not menstruate in the first place, they cannot go through menopause. Only primates, such as humans and chimps, menstruate. (Cats will bleed a little while in heat, but this is part of the estrous cycle, which is not the same. Estrus in cats is closer to the period right after menstruation in humans.) They don't even go through menopause in the sense of ceasing to experience estrus; cats remain fertile throughout life.
Do mammals have more changes in their life cycle than insects or amphibians?
Mammals actually have less changes in their life cycle than insects or amphibians. Humans go through about three stages of significance in their life time.
Do bobcats go through metamorphosis?
No, bunnies do not go through metamorphosis.
