Reproductive MethodGiant Pandas’ do have a very common reproductive system. This is as they are a mammal, like many others.
The Giant Panda’s will travel to find a mate, throughout long distances. Firstly, the mates will fight each other for the female.Secondly, they will mate throughout the months of March and May and the males may mate with many females. Thirdly, the female and the male will spend 2 to 3 days and then part ways.Afterwards, the giant panda offspring is given birth to 95 to 165 days later and this will most often be a single cub. Lastly, the giant pandas will grow up and leave their mother when she is pregnant, which tends to be 18 to 24 months, then the system starts again. |
Method of FertilisationInternal fertilization is when an egg cell unites with a sperm cell inside the organism and this is what happens for the giant panda’s fertilization. A Giant Panda’s method of fertilisation is internal as the sperm unites with inside of the female giant panda, not outside or in an egg. Therefore, the female Giant Panda will give birth to the offspring inside of themselves.
|
Frequency of Reproduction and Number of OffspringFemale Giant Panda’s ovulate once per every year, and this provides them with the only chance to mate. This causes a low breeding process and will maintain a lower population of Giant Panda. This being said, the Giant Panda species is endangered as of these low frequencies of reproduction. The number of offspring of a Giant Panda reproduces is usually one cub or pairs. If the mother Giant Panda reproduces pairs, this will lead to the parent choosing a favorite and letting it live whilst the other perishes. This is as, the mother cannot support pairs of cubs and can only support one. The average frequency of reproduction and number of offspring is one per two years.

Development of Offspring from Fertilisation to Birth |
Parental Care and Survival of Offspring |
After the offspring is born, they are useless and cannot fend or practically do anything for themselves. The mother of the offspring has to fend and care for the offspring until they develop their power to care for themselves. The offspring is in need of upbringing socially and nutritionally and this is lead down to the mother needing to teach the offspring these skills. The upbringing socially varies reality around one year and the upbringing nutritionally varies around two years.
|
Newly born offspring carefully and fully rely on their mother to survive in the world. Baby Giant Pandas are incapable to feed themselves and take care for themselves, therefore creating low survival chances. If there is more than one offspring, the mother will decide the favorite and let them survive whilst the other perishes. This leaves the mother to take care and be responsible for the offspring whilst protecting it from hazards. If the mother of the offspring is incapable of this, then they will have to let human activity care for the offspring.

Emperor Penguins
Reproductive SystemThe reproductive system of the Emperor Penguin is unlike any of its species. They only reproduce during the peak of winter at the Antarctic.
They will move to the breeding season prime area, which could be as far as 70 miles. They would then meet thousands of other penguins and find a mate. The pair would stay together for a year. Afterwards, the female will lay an egg and the male is left to care about it This is done by a transfer process which could end in a successful account or a bad account in which the egg is left in the cold and destroyed. Then, the female will leave to attempt to gain food for the offspring and the male. Lastly, the females will come back and will return to during the first week of the offspring’s birth then will become the caregiver. |
Method of FertilisationExternal method of fertilisation is the sperm will fertilise the egg outside of the substance. The emperor penguin consists of external fertilisation as the offspring is born from an egg, outside of the emperor penguin. This egg will then hatch releasing the offspring inside.
|
Frequency of Reproduction and Number of OffspringBreeding season for the Emperor Penguins is usually in May or early June. The frequency of reproduction for Emperor Penguins is one offspring per year. This may vary as some other penguins can differ and reproduce two or three per year. In this duration of time, they will externalize an egg and that will be their only offspring. Therefore, the frequency of reproduction for Emperor Penguins is once per a year, and the amount of offspring is average one as they cannot afford to feed more than one.
|
Development of Offspring from Fertilisation to Birth
The parents of the penguin provide large amounts of care towards their offspring for many reasons. This can be as emperor penguins regurgitate their food for the offspring. Also, the males provide a curd like substance from their oesophagus to the offspring to provide survival and growth for two weeks. Emperor Penguin offspring usually do not have sufficient warmth when given birth to so therefore, the parents provide warmth with their brood patch. The mother would usually leave to gain food for the offspring and parent then, would come back and care for the offspring with warmth.
|
Parental Care and Survival of OffspringThe adults forage and provide the chick with the warmth and food that is needed until the chick can molt. This is as the chick does not have feather and cannot suffice warmth for itself and hunt for themselves, therefore leaving the parents to. This may vary from huddling with the chick for long periods of time, the male regurgitating a white substance that will provide the chick with food for two weeks and lastly, the female scourging for food.
