How many egg cells does a female sheep have ready for fertilisation before mating occurs?
A female sheep typically has around 400-500 egg cells ready for fertilization before mating occurs. These egg cells are stored in the sheep's ovaries and are released during the estrous cycle for potential fertilization. Each estrous cycle typically releases one egg cell for potential fertilization, but multiple egg cells can be released in some cases.

Where fertilisation occurs in a butterfly?
Fertilization in butterflies occurs inside the female butterfly's body during the mating process. After copulation, the male transfers sperm to the female's reproductive system, where it fertilizes the eggs as they are being laid.
Is blackbird external fertilisation?
No, blackbirds do not use external fertilization; they reproduce through internal fertilization. Female blackbirds lay eggs after mating with a male, and fertilization occurs inside the female's body. The female then nests and incubates the eggs until they hatch.
Does fertilisation take place inside or outside the cats body?
Fertilization in cats typically occurs inside the female's body in the oviducts during mating. The female's eggs are fertilized by the male's sperm within the reproductive tract.
What is the fossa mating ritual?
During the mating ritual, male fossas compete for female attention by engaging in vocalizations, scent marking, and physical displays of strength. They may also engage in playful interactions to establish trust and compatibility with the female before mating occurs. The mating process itself involves the male mounting the female from behind to copulate.
What are the Barramundi courtship behaviors before mating?
Male Barramundi exhibit courtship behaviors such as chasing and nudging the female, as well as displaying their fins and colors to attract her. They may also establish territories and perform courtship dances to impress the female before mating. Mating typically occurs when the female is ready to release her eggs and the male fertilizes them externally.
Can the female rottweiler get pregnant before day 8?
Yes, a female Rottweiler can become pregnant before day 8 of her heat cycle. Typically, a female dog is most fertile during the estrus phase, which usually occurs around days 9 to 14 of her heat cycle, but sperm can survive in the female's reproductive tract for several days. Therefore, mating can result in pregnancy if it occurs before the peak fertility days.
What type of fertilisation occurs in elephants?
Like all mammals, elephants employ internal fertilisation.
Does pollination occur before fertilisation?
Yes, pollination is the process of transferring pollen grains from the male reproductive organs of a flower to the female reproductive organs. Fertilization occurs after pollination, when a pollen grain meets the ovule of a flower and forms a seed.
When the pollen lands on an egg is this pollination or fertilisation?
When pollen lands on an egg, it is the beginning of the fertilization process. Pollination is the process of moving pollen from the male part of a flower to the female part, while fertilization occurs when the sperm from the pollen reaches and fertilizes the egg.
The stage of the estrus cycle in which no active reproduction occurs is called?
Anestrus or Diestrus. Proestrus is when the female is about to go into estrus, and Metestrus is the period before Diestrus and after Estrus which the female goes out of heat and ovulation ends.
What is a external fertalisation?
External fertilization occurs when the egg is fertilized by the sperm outside of the female's body. As when a female fish deposits her eggs on the ground and the male fish ejaculates his sperm over the eggs. Internal fertilisation occurs when the sperm fertilizes the egg inside the female's body. Which is what mammals do, including human beings.
Is fertilisation of a white tiger internal or external?
