Asexual and Sexual Reproduction

• Sexual reproduction involves two parents, genetic recombination through gamete fusion, and the formation of zygotes with unique combinations of genes.
• Asexual reproduction is the production of offspring from one parent without sexual intercourse.
• Advantages of asexual reproduction include rapid population growth, no need to find mates or compete for them, and the ability to produce genetically identical offspring that are clones of their parents.
• In asexual reproduction, there are no offspring that do not inherit all the characteristics of their parent(s).
• offspring may grows out of its parents body through a process called budding
• Gemmule Formation is internal budding where a bud grows out of its parents internal body structure
• Fission is when the parents body break into 2 distinct parts the head and the tail those parts will then form 2 exact copies of the parent
• Fragmentation is the ability to reproduce from fragments depending on the size that broke of
• internal fertilization occurs in the females body
• external fertilization happens outside the female, female lays egg and the male releases its sperm to fertilize the egg
• internal fertilization- when fertilized the zygote develops into a embryo
• internal fertilization - the embryo is protected and nourished inside the females body
• internal fertilization - the offspring has a better chance surviving in the parents body
• external fertilization - the offspring has a lower chance of surviving in the wild because it is exposed to predators
• the embryo receives nourishment through an organ called placenta
• animals that give birth to live offspring means they are called viviparous animals
• offspring protected inside a egg are called oviparous animals
• eggs contain yolk which provides food to the offspring
