Organisms that can reproduce with or without fertilization of eggs are typically referred to as capable of asexual and sexual reproduction. For example, certain species of plants, such as strawberries, can reproduce asexually through runners while also having the ability to reproduce sexually through seeds. Additionally, some animals, like certain types of reptiles and amphibians, can reproduce parthenogenetically, meaning they can develop eggs into offspring without fertilization. This flexibility in reproduction allows these organisms to adapt to varying environmental conditions.
if you mean eggs you buy in a store, then no, because these eggs were conceived by the bird without male fertilisation.
No, without fertilisation (mating) the egg will not develop further.
fertilisation
external fertilisation
Yes
internal
The simple answer is Yes.
Pandas are mammals and reproduce sexually by internal fertilisation.
Most fish reproduce using external fertilisation - the female lays her eggs, and the male then covers them with sperm, fertilising them. Some fish, however, use internal fertilisation. Sharks are an example. Males sharks have paired copulatory organs called claspers, one of which is inserted into the female's cloaca, depositing sperm inside her. In some species, eggs are then laid and will hatch after an incubation period, but in others the eggs are retained within the mother's body until the young are fully developed, when they are born alive.
Sea urchins generally have separate sexes and spawn seasonally every year. Eggs and sperm are usually released to the water column where fertilisation occurs.
Parthenogenesis is a type of asexual reproduction where organisms can reproduce without their eggs being fertilized by sperm. This is common in species such as reptiles, insects, and fish.
