Animals use various reproductive organs depending on their species. In mammals, females typically have a uterus where offspring develop, while males have testes that produce sperm. Birds, reptiles, and some fish have different structures, such as ovaries and cloacas, for reproduction. Overall, the specific organs and processes vary widely across the animal kingdom.

Lamarck.
Jean-Baptiste Lamarck proposed the theory of the inheritance of acquired characteristics, which suggests that the use or disuse of an organ could lead to changes in that organ that are then passed on to the offspring. This theory was later found to be inaccurate in light of modern genetics and the principle of inheritance through DNA.
No, not all animals need to mate to have offspring.
Whenever one refers to an animals or humans offspring, such as; The mare's progeny were successful racehorses. Progeny is a fancy word for offspring.
There is no opposite of Whiskers on animals. They are a sense organ and many animals have them. Animals without Whiskers use other senses instead. Beardless
Offspring
Jean-Baptiste Lamarck proposed this idea in his theory of inheritance of acquired characteristics. He suggested that organisms could pass on traits acquired during their lifetime to their offspring, leading to evolutionary change.
The females do the rearing of the offspring. In fact, some male animals are known for eating their own offspring, like Lions. Males are usually highly aggressive to their offspring.
Animals use different types of organs for protection. For instance, the skin is the largest organ of the animals that is generally used to protect the inner parts of the animals.
The 'offspring' for animals refers to their young.
The offspring of different animals are known by different names- for example the oppsring of a Lion is called a cub, that of a cow is called a calf and so on.
