Parasitic Twin
A parasitic twin, also known as an asymmetrical twin or unequal conjoined twin, occurs when a twin embryo begins developing in utero, but the pair does not fully separate, and one embryo maintains dominant development at the expense of the other. It results from the same processes that also produces '' vanishing twins'' and ''conjoined twins'', and may represent a continuum between the two. In parasitic twins, one ceases development during gestation and is vestigial to a mostly fully formed, otherwise healthy individual twin. The undeveloped twin is termed as '' parasitic'', because it is incompletely formed or wholly dependent on the body functions of the complete fetus. The independent twin is called the autosite. The autosite, together with the parasite, are collectively referred to as heteropagus twins. Variants TRAP sequence The twin reversed arterial perfusion, or TRAP sequence, results in an 'acardiac twin', a parasitic twin that fails to develop a head, arms and a heart ...

Conjoined Twin
Conjoined twins, popularly referred to as Siamese twins, are twins joined ''Uterus, in utero''. It is a very rare phenomenon, estimated to occur in anywhere between one in 50,000 births to one in 200,000 births, with a somewhat higher incidence in southwest Asia and Africa. Approximately half are stillbirth, stillborn, and an additional one-third die within 24 hours. Most live births are female, with a ratio of 3:1. Two possible explanations of the cause of conjoined twins have been proposed. The one that is generally accepted is ''fission'', in which the fertilized egg splits partially. The other explanation, no longer believed to be accurate, is ''fusion'', in which the fertilized egg completely separates, but stem cells (that search for similar cells) find similar stem cells on the other twin and fuse the twins together. Conjoined twins and some monozygotic, but not conjoined, twins share a single common chorion, placenta, and amniotic sac ''in utero''. Chang and Eng Bunker (1 ...

Germans
Germans (, ) are the natives or inhabitants of Germany, or sometimes more broadly any people who are of German descent or native speakers of the German language. The Basic Law for the Federal Republic of Germany, constitution of Germany, implemented in 1949 following the end of World War II, defines a German as a German nationality law, German citizen. During the 19th and much of the 20th century, discussions on German identity were dominated by concepts of a common language, culture, descent, and history.. "German identity developed through a long historical process that led, in the late 19th and early 20th centuries, to the definition of the German nation as both a community of descent (Volksgemeinschaft) and shared culture and experience. Today, the German language is the primary though not exclusive criterion of German identity." Today, the German language is widely seen as the primary, though not exclusive, criterion of German identity. Estimates on the total number of Germ ...

Lakshmi Tatma
Lakshmi Tatma is an Indian girl born in 2005 in a village in Araria district, Bihar, with four arms and four legs. She was actually one of a pair of ischiopagus conjoined twins, one of which was headless because its head had atrophied and chest had not fully developed in the womb, causing the appearance of one child with four arms and four legs. She has undergone surgery to remove these extra limbs. Background Lakshmi's father, Shambhu, and mother, Poonam, were day labourers who earned less than 40 rupees per day and were unable to afford a separation surgery for their daughter. The daughter was named after Lakshmi, the Hindu goddess of wealth (who is depicted as four-armed). The girl was sometimes an object of worship as an incarnation of the goddess; by the age of two, she was known all over India. At one point, a circus offered the couple money to buy Lakshmi as a sideshow, which forced the family into hiding. At the time of being found by Sharan Patil, she had an infecte ...

Dipygus
Caudal duplication, (or caudal duplication syndrome) is a rare congenital disorder in which various structures of the caudal region, embryonic cloaca, and neural tube exhibit a spectrum of abnormalities such as duplication and malformations. The exact causes of the condition is unknown, though there are several theories implicating abnormal embryological development as a cause for the condition. Diagnosis is often made during prenatal development of the second trimester through anomaly scans or immediately after birth. However, rare cases of adulthood diagnosis has also been observed. Treatment is often required to correct such abnormalities according to the range of symptoms present, whilst treatment options vary from conservative expectant management to resection of caudal tissue to restore normal function or appearance. As a rare congenital disorder, the prevalence at birth is less than 1 per 100,000 with less than 100 cases reported worldwide. The term "caudal duplication synd ...

Sheep
Sheep (: sheep) or domestic sheep (''Ovis aries'') are a domesticated, ruminant mammal typically kept as livestock.

An adult female is referred to as a ''ewe'' ( ), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat ( lamb, hogget or mutton), and milk.

Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated subspecies of the red junglefowl (''Gallus gallus''), originally native to Southeast Asia. It was first domesticated around 8,000 years ago and is now one of the most common and widespread domesticated animals in the world.

As of 2023, the global chicken population exceeds 26.5 billion, with more than 50 billion birds produced annually for consumption. Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively. A hen bred for laying can produce over 300 eggs per year. Chickens are social animals with complex vocalizations and behaviors, and cultural references to chickens, feature prominently in folklore, religion, and literature across many societies.
