Hint: In citrus fruit, the phenomenon of polyembryony was discovered for the first time. The rise of the enigma of a single offspring in plants is often done by polyembryony. Regularly in many plants and animals, polyembryony takes place.
Complete answer:
In the year 1719, the natural polyembryony phenomenon was discovered by Antoine van Leeuwenhoek for the first time.
The word polyembryony means the development of many embryos. Polyembryony is the phenomenon where a single fertilized egg is developed into two or more two embryos. Identical twins are the result of the case of humans. In both plants and animals, the polyembryony phenomenon is observed.
In the animal kingdom, the nine-banded armadillo is the best example of polyembryony. In certain parts of America, the nine-banded armadillo is the medium-sized mammal that is found. Identical quadruplets offspring are the resultants in some cases.
In plants, polyembryony phenomena give the resultant to the offspring when one or more than one embryonic sac is fertilized.
The polyembryony phenomenon is classified into two types:
> Induced polyembryony
> Spontaneous polyembryony.
The Induced polyembryony is the resultant of the experimentally induced phenomenon where the spontaneous polyembryony is the naturally occurring phenomenon.
There is another classification of polyembryony phenomena according to Webber.
> Cleavage polyembryony
> Simple polyembryony
> Rosette polyembryony.
Note:
In polyembryony phenomena, from the parents the genetically diverse. Between the offspring and the parents, there is a genetic difference but the genetic similarity occurred among siblings. In many species of vertebrates, invertebrates, and many plants the polyembryony occurs regularly.
