Corals can be both gonochoristic (unisexual) and hermaphroditic, each of which can reproduce sexually and asexually. Reproduction also allows corals to settle new areas. Corals predominantly reproduce sexually. 25% of hermatypic corals (stony corals) form single sex (gonochoristic) colonies, while the rest are hermaphroditic. [156]
Female domestic cats can have kittens from spring to late autumn in temperate zones and throughout the year in equatorial regions, with litter sizes often ranging from two to five kittens. Domestic cats are bred and shown at events as registered pedigreed cats , a hobby known as cat fancy .
Estrous cycle variability differs among species, but cycles are typically more frequent in smaller animals. Even within species significant variability can be observed, thus cats may undergo an estrous cycle of 3 to 7 weeks. [15] Domestication can affect estrous cycles due to changes in the environment.
Kitten season is the time of year during which cats are more likely to mate and reproduce at a higher rate. Female cats are “seasonally polyestrous,” meaning they only go into heat at certain ...
Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. [6] [7] Sexual reproduction also occurs in some unicellular eukaryotes. [2] [8] Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such as bacteria and archaea.
[4] [5] This leads males to evolve aggressive mating behaviors which can help them acquire mates. [5] Sexual coercion has been observed in many clades, including mammals, birds, insects, and fish. [6] While sexual coercion does help increase male fitness, it is very often costly to females. [5]
Cats tend to stop growing once they've reached 1 year old. A 12-month-old cat is equivalent in age to a 15-year-old human, according to PetMD. But some cats do continue to grow past the 12-month mark.
The word is most often used for the offspring of mammals, but can be used for any animal that gives birth to multiple young. In comparison, a group of eggs and the offspring that hatch from them are frequently called a clutch, while young birds are often called a brood. Animals from the same litter are referred to as littermates.
