Examples of sexual reproduction in the following topics:
-
- Animal reproduction is essential to the survival of a species; it can occur through either asexual or sexual means.
- The known methods of reproduction are broadly grouped into two main types: sexual and asexual.
- This type of reproduction produces genetically-identical organisms (clones), whereas in sexual reproduction, the genetic material of two individuals combines to produce offspring that are genetically different from their parents.
- Sexual reproduction ensures a mixing of the gene pool of the species.
- In addition, sexual reproduction usually results in the formation of a life stage that is able to endure the conditions that threaten the offspring of an asexual parent.
-
- The genetic diversity of sexual reproduction, observed in most eukaryotes, is thought to give species better chances of survival.
- Sexual reproduction was an early evolutionary innovation after the appearance of eukaryotic cells.
- Scientists recognize some real disadvantages to sexual reproduction.
- There are several possible explanations, one of which is that the variation that sexual reproduction creates among offspring is very important to the survival and reproduction of the population.
- Variation is the outcome of sexual reproduction, but why are ongoing variations necessary?
-
- Plants have developed various strategies, both sexual and asexual, to ensure reproductive success.
- Some plants reproduce sexually while others reproduce asexually, in contrast to animal species, which rely almost exclusively on sexual reproduction.
- Plant sexual reproduction usually depends on pollinating agents, while asexual reproduction is independent of these agents.
- Vegetative reproduction is a type of asexual reproduction.
- The basic function of a flower is to produce seeds through sexual reproduction.
-
- Meiosis is the nuclear division of diploid cells into haploid cells, which is a necessary step in sexual reproduction.
- Sexual reproduction requires fertilization: the union of two cells from two individual organisms.
- Therefore, sexual reproduction includes a nuclear division that reduces the number of chromosome sets.
- Sexual reproduction is the production of haploid cells (gametes) and the fusion (fertilization) of two gametes to form a single, unique diploid cell called a zygote.
- Haploid cells that are part of the sexual reproductive cycle are produced by a type of cell division called meiosis.
-
- In both sexual and asexual reproduction, fungi produce spores that disperse from the parent organism by either floating on the wind or hitching a ride on an animal.
- Sexual reproduction introduces genetic variation into a population of fungi.
- In fungi, sexual reproduction often occurs in response to adverse environmental conditions.
- Although there are many variations in fungal sexual reproduction, all include the following three stages .
- Fungi may utilize both asexual and sexual stages of reproduction; sexual reproduction often occurs in response to adverse environmental conditions.
-
- Asexual and sexual reproduction, two methods of reproduction among animals, produce offspring that are clones or genetically unique.
- The queen bee controls the reproduction of the hive bees to regulate the type of bee produced.
- Sexual reproduction is the combination of (usually haploid, or having a single set of unpaired chromosomes) reproductive cells from two individuals to form a third (usually diploid, or having a pair of each type of chromosome) unique offspring.
- Sexual reproduction produces offspring with novel combinations of genes.
- Hermaphroditism occurs in animals where one individual has both male and female reproductive parts.
-
- Sexually-reproducing organisms have evolved specialized gonads, along with a variety of ways to transfer sperm during reproduction.
- Several competing scientific hypotheses have been proposed to explain the evolution of sexual reproduction.
- All sexually-reproducing eukaryotic organisms derive from a common ancestor that was a single-celled eukaryotic species.
- Many protists reproduce sexually, as do multicellular plants, animals, and fungi.
- However, since the hypotheses for the origins of sex are difficult to test experimentally, most current work has been focused on the maintenance of sexual reproduction.
-
- Reproductive cloning, possible through artificially-induced asexual reproduction, is a method used to make a clone of an entire organism.
- Most multicellular organisms undergo reproduction by sexual means, which involves genetic hybridization of two individuals (parents), making it impossible to generate an identical copy or clone of either parent.
- Sexual reproduction requires two cells; when the haploid egg and sperm cells fuse, a diploid zygote results.
- This idea forms the basis for reproductive cloning.
- The success rate of reproductive cloning at the time was very low.
-
- Traditionally, these plants survive well under stable environmental conditions when compared with plants produced from sexual reproduction because they carry genes identical to those of their parents.
- Plants have two main types of asexual reproduction: vegetative reproduction and apomixis.
- Many different types of roots exhibit vegetative reproduction .
- This method of reproduction is known as apomixis.
- Different types of stems allow for asexual reproduction.
-
- Sexual selection, the selection pressure on males and females to obtain matings, can result in traits designed to maximize sexual success.
- These differences are called sexual dimorphisms and arise from the variation in male reproductive success.
- Sexual selection can be so strong that it selects for traits that are actually detrimental to the individual's survival, even though they maximize its reproductive success.
- This male bird of paradise carries an extremely long tail as the result of sexual selection.The tail is flamboyant and detrimental to the bird's own survival, but it increases his reproductive success.This may be an example of the handicap principle.
