š Can animals give birth to twins š
Ask any parent ā if the family has to welcome a new baby, they will say it's a joy; But, with that, it will be too much work. So, what if the new addition is a pair of babies, that is, twins? Parents have to make real sacrifices to get their work done. If you take many animal species, it is normal to give birth to several children (pats) at the same time. However, pig mothers give birth to 11 or more babies at the same time!
š Pigs are one of the species that give birth to a large number of offspring. š
We are faculty members of the Mississippi State University College of Veterinary Medicine. Over the years we have seen cases of puppies and kittens being born to it. And animal mothers almost always give birth to multiple litters ā so all those litters that share the same birthday ā are siblings twins?
Twins are two bones in one pod
Twins are defined as two children born from the same pregnancy. The twins may be identical, meaning that one sperm fertilizes one egg, which splits into two separate cells and develops into two identical babies. They share the same DNA, which is why the two twins are indistinguishable from each other. Twins can also be fraternal twins. It is the result when two separate eggs are fertilized individually at the same time. Each twin has an identical set of genes from both mother and father. One can be male or female. Fraternal twins are basically like any set of siblings.
Fraternal (fraternal) twins are born from two separate fertilized eggs, while identical twins create two embryos from one fertilized egg. Approximately 3% of human pregnancies in the United States result in twins. Most of them are fraternal twins. Approximately one out of every three pairs of twins is an identical twin.
Multiple litters from one mother animal
Each animal species has its own standard number of offspring per birth. People tend to know more about domesticated species that are kept as pets or farm animals. Among domestic dogs, one study that surveyed more than 10,000 litters found that the average number of puppies varies by breed. Smaller breeds of dogs, such as chihuahuas and toy poodles ā usually weighing less than 10 pounds (4.5 kg) ā typically have 3.5 litters per bull. Large breeds of dogs, such as mastiffs and Great Danes, which usually weigh more than 100 pounds (45 kg), usually have more than seven litters per litter.
When there are only two puppies in a litter, for example, people tend to call the two puppies twins. Although a mother goat can give birth to a single kid or multiple kids. Twins are the most common outcome that can be expected from a pregnant goat mother. Ewes often give birth to twins, but singleton lambs are also common. Like horses, which have a gestation period of 11 to 12 months, cows, which are pregnant for nine to 10 months, usually give birth to only one calf at a time, but can have twins. Veterinarians and farmers have long believed that encouraging twin conceptions among dairy and beef cattle would be financially beneficial. Basically because the farmer gets two calves for the cost of one pregnancy. However, twinning between cows carries the risk of birth complications for the cow and small calves with low survival rates. Twin pregnancies in horses come with similar risks of both pregnancy complications and the birth of weak foals.
** DNA Holds the Answer to What Kind of Twins **
Therefore, many animals can give birth to twins. The more complicated question, however, is whether two animals born together are identical (identical) or fraternal twins. Despite being born in the same litter, these kittens have different sets of genes. Females of dogs and cats produce several eggs (eggs) at a time. Multiple embryos are produced by fertilization of individual eggs by specific sperm of a male. As a result of this process, although the puppies or kittens look very similar, they are non-identical siblings.
Biologists believe that identical twins are very rare among most animals. The hard thing to understand is that, often, animal siblings are very similar in appearance. To confirm whether two offspring actually share all of their genes, researchers need to perform a DNA test. DNA testing has confirmed the existence of identical, or identical, twin dogs with only one documented record of the branch. But no one knows for sure how many times a fertilized animal's egg divides to become an identical twin.
Also, reproduction is different between different animals. For example, armadillos with nine arms usually give birth to identical quadruplets
