external fertilization
The two types of fertilization are 1. Internal fertilization 2. External fertilization Internal fertilization takes place within the body of the female. External fertilization takes place outside the body of female. It takes place by layong eggs.
These terms are fairly intuitive. External means outside. Internal means inside. Fertilization occurs when the male gamete (sperm) meets the female gamete (egg). External fertilization is fertilization that occurs outside the body, whereas internal fertilization is fertilization that occurs inside the body (usually the body of the female).
Tigers have Internal Fertilization. (occurs inside the body). Tigers copulate frequently and noisily and repeatedly for 5 or 6 days. Each usually take about 20 to 30 seconds. Then the gestation period is 16 weeks.

Internal fertilization is a process in which the fertilization of an egg by sperm occurs inside the body of a female organism. This typically involves mating or copulation between males and females to transfer sperm to the female reproductive tract for fertilization to occur. Internal fertilization is common in mammals, reptiles, birds, and some fish.
External fertilization typically occurs in aquatic environments, where eggs and sperm are released into the water. This method is common in many fish and amphibian species, allowing sperm to swim to the eggs for fertilization. In contrast, internal fertilization occurs inside the body of the female, common in terrestrial animals like mammals and reptiles, where sperm fertilizes the egg within the reproductive tract.
In humans, fertilization occurs in the ampulla of the uterine tube. During fertilization the sperm and the egg become one and become what is called a zygote.
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.
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.

Beetles typically exhibit internal fertilization. During mating, the male transfers sperm to the female's reproductive tract, where fertilization occurs inside her body. This method allows for greater protection of the developing embryos compared to external fertilization, which is common in some other species.
Most amphibians have external fertilization, so outside the body.
