Yes. Like kangaroos, rock-wallabies do have embryonic diapause. They may indeed keep the development of the embryo in suspension until the optimum time for birth.
Embryonic diapause is, in layman's terms, the ability of a female kangaroo to suspend the development of the embryo during gestation so that it is not born when conditions might compromise its survival, e.g. during drought. Almost all marsupial macropods have the unique feature of embryonic diapause, especially the larger and mid-sized species, such as the red kangaroos, and also many species of wallabies. Even Gilbert's potoroo, a smaller macropod, exhibits embryonic diapause. The smallest member of the kangaroo family, the musky-rat kangaroo, does not appear to have embryonic diapause; nor do some of the tree kangaroos.
Diapause, has great advantages to the species in that if one young dies, another embryo can quickly take its place.
The mother kangaroo spends most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished. This is called embryonic diapause. Quite simply, the young joey will not be born until or unless there is enough food to nourish the mother and, through her, the suckling joey.
Generally, wallabies give birth to a single joey in one year. However, almost all wallabies have the unique feature of embryonic diapause, which means they can actually give birth more often. What this means is that the mother wallaby spends most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished. This is the same with kangaroos, and is called embryonic diapause.

This is called embryonic diapause. The mother kangaroo spends most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished. It enables survival of the species.
Diapause is a period of time when an insect does not grow. It is especially effective and efficient when food and water are scarce.
give me the answer please

Embryonic Soul was created in 1998.
There are many different species of wallaby but, on average, they have a gestation period of 30 days and spend 8-9 months in the pouch.However, in reality, pregnancy length may differ. The mother wallaby may spend most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished. This is called embryonic diapause.
Embryonic induction and its clinical important?
