CERES Zoo Zoo

Two parent organisms are involved-the male and female. When an egg cell unites with the sperm cell, a zygote (new cell) is formed. SEXUAL REPRODUCTION is a process of creating offspring with the participation of sperm cell from the male parent and egg cell from the parent.

inside and outside the body are two general modes of sexual reproduction. The expected offspring may have separate (single) sex or combined sexes spending on the species. FERTILIZATION Unique individual possessing different characteristics is produced in sexual reproduction because the genetic materials of the parents are blended (combined).

Through the process, the offspring is thought to give sexually reproducing individuals with greater fitness to be mechanism to survive and reproduce in an unpredictable or changing environment. FERTILIZATION

TWO WAYS Sexual Reproduction Sexual Reproduction

is the union of an egg and sperm cell during the sexual reproduction inside the female body. Internal Fertilization occurs within the body of the female. It takes place when a specialized sex organs transfers the sperms from the body of the male into the body of the female.

Is a mode of reproduction in which a male organism’s sperm fertilizes a female organism’s egg outside of the female’s body. External Fertilization The eggs are fertilized in the environment, outside the body of the female. It usually occurs in the most aquatic invertebrates, all fish in general, except for sharks, rays and many amphibians.
