A Brief Discussion On Animal Reproduction

Animal Reproduction

In the animal world, every species has unique adaptations required for reproduction. Sexual and asexual reproduction is the two kinds. Asexual reproduction is known for producing offspring that is genetically identical. As far as sexual reproduction is concerned, the genetic materials of both individuals are combined for the production of offspring which are not different from other parents in terms of genetics. During reproduction, the gamete is placed inside the body for fertilization that takes place internally. The male gamete is left for a female to pick it up to place it in her body and eggs and sperm is released for fertilization to take place externally.

Overview of sexual and asexual reproduction

There are some animals which produce offspring with the help of asexual reproduction, whereas others do it through sexual reproduction. However, both methods have its own pros and cons. A sexual reproduction helps in offspring production that is identical genetically of the parent as the offspring are basically clones of the actual parent. In fact, a single individual easily produces offspring through asexual method and offerings can be produced in large numbers in no time. These are the key benefits of asexual reproduction over sexual reproduction.

Pros & cons

In a normal environment, one of the effective methods of reproduction is the asexual one as the offspring are well adapted to such conditions. Whereas, under unpredictable environment, animals may reproduce through asexual methods, but it is more of a disadvantage as all offspring are identical and adapting to distinct conditions is not possible.

The genetic material of distinct individuals is mixed for production of genetically different offspring so as to ensure they are not identical to their parents. This is the normal scenario that takes place during sexual reproduction. The diverse offspring produced here is known to offer better fitness as the offspring can sustain and reproduce even in a distinct or unpredictable environment. It is important to maintain different types of individuals which includes both male and female when they reproduce sexually. Only half the female species are capable of producing offspring and hence limited production of offspring takes place when you compare it with asexual reproduction. Well, this is a constraint of sexual reproduction over asexual reproduction. These are some of the basics of animal reproduction that you should be aware of especially if you are an animal lover and wish to have pets.
