Sexual reproduction is a type of life cycle where generations alternate between cells with a single set of chromosomes and cells with a double set of chromosomes . Sexual reproduction is by far the most common life cycle in eukaryotes, for example animals and plants.
Individual organisms come and go, but, to a certain extent, organisms transcend time through producing offspring. Reproduction in animals occurs in two primary ways, through sexual reproduction and through asexual reproduction.. While most animal organisms reproduce by sexual means, some are also capable of reproducing asexually.
Animals who practice sexual reproduction can be differentiated according to whether they are viviparous animals or oviparous animals; this depends on the way they carry the embryo.There are some who do this internally, i.e. the foetus develops within the stomach of the mother (as with people) and others for which egg development is external.
No, animals either reproduce sexually or asexually. In sexual reproduction, two parents are required and an offspring is born with inherited genes/characteristics of both parents.
Although sexual reproduction is a more common method of reproduction among animals, a few species, such as starfish and sea anemones, produce offspring via asexual reproduction. Asexual reproduction, in contrast to sexual reproduction, does not require the mating of two parents to produce an offspring.
Some animals produce offspring through asexual reproduction while other animals produce offspring through sexual reproduction. Both methods have advantages and disadvantages. Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.
When animal sexual behaviour is reproductively motivated, it is often termed mating or copulation; for most non-human mammals, mating and copulation occur at oestrus (the most fertile period in the mammalian female's reproductive cycle), which increases the chances of successful impregnation.
Reproduction is how organisms pass on their genes. While some organisms reproduce only sexually or asexually, there are many that do both. This lesson will explore the benefits of this strategy ...
No species of animal can live forever, so it needs to reproduce. In this lesson we'll talk about how animals reproduce, and some of the pros and cons of the different types of reproduction. 2016-01-02
Asexual reproduction can be very advantageous to certain higher animals and protists. Organisms that remain in one particular place and are unable to look for mates would need to reproduce asexually. Another advantage of asexual reproduction is that numerous offspring can be produced without "costing" the parent a great amount of energy or time.
