Is the reproduction of an organism without the fusion of gametes (sperm and egg)Production of a new organism without a 2 party interaction for fertilization

What is asexual reproduction?Budding- The asexual process of budding can be explained a organism leaching /developing off another organism

- Hydra use this form of Asexual reproduction to produce new organisms

Is the development of offspring from unfertilized eggsFemales can act as males in some speciesProduce a hormone that can fertilize their eggs in absence/abundance of male populationYou see rotifers use this method to sometimes produceParthenogenesisDoes not require matingLittle genetic diversity in the reproductionYou usually see this in sessile invertebrates that live in constant environmentsYou see this form of reproduction in bacteria and other single celled organisms

Asexual reproduction- Required for the rise of the germ cells- Process in which diploid of cell turns haploid for both mother and father before fertilizationThis process occurs in the gonads Ovaries in femalesGametes are larger and sessile

Testes in malesGametes are small and motile

Gametogenesis

GametogenesisInvolves a special type of cell division called meiosisProcess of genetic material from the parents being cut in halfMatingThe pairing of the opposite sex for copulationCopulation is the union of the sex organs of two sexually reproducing animals for insemination and fertilizationFertilizationThe union of haploid egg and sperm in production of a zygote, or fertilized eggSteps of fertilization (Sexual)Star fish, lizards, planarians, sharks, spiders amongst many other organisms that regenerate for reproductionMany organisms can regenerate that is, regrow or grow new parts of their bodies to replace those that have been damaged.http://www.factmonster.com/ipka/A0768606.html

regeneration

Sexual vs. AsexualAsexualSexualRequires the union of 2 individuals to produce offspring (male & female)Wide range of genetic variation in offspringOnly mammals use this form of reproduction

Only requires 1 parent to produce offspringLittle genetic diversity seen in daughter organismsOnly bacteria and single celled organisms use this
