TWIN CHILDREN FROM TWIN MOM AND TWIN DAD

 Identical twins have identical DNA, and they share genes. Sometimes they may not be similar, and sometimes they are very similar to each other, almost like mirror images and they are apart only by their fingerprints, teeth, handwriting, or any other intricate observations. Twins share the same womb at the same time, and have come from the same egg. But it is not necessary to have mirror images from the same womb.

What are Double Cousins?

Identical cousins or double cousins are when two twins of one family have children with two twins of another family. With this, the question arises that is it possible to have a twin cousin. Yes, as the children are identical to each other as both of their parents and are considered double related. 

Role of DNA and Genes

Deoxyribonucleic acid is a genetic material that contains all the information which is necessary to an organism. All living things have DNA in their cells. In fact, every cell in a multicellular organism possesses the full set of DNA required for an organism.

DNA is the genetic blueprint of the organisms. DNA exists in a stable structure called double-helix and is organized into chromosomes. Genes are the hereditary molecules which transfer traits. Genes are composed of DNA or RNA stretches. The key difference between DNA and genes is that DNA is a chemical structure which stores the genetic instructions and genes are small DNA stretches which determine a specific trait.

A gene is a region or a specific nucleotide sequence on the DNA strand. Genes encode an amino acid sequence of a particular protein. Thousands of genes are found within a single DNA molecule of higher organisms.

Children of twins depend on what kind of twins parents are. If both twins are fraternal twins, which means that they came from two different eggs, then they are brothers who were born on the same day. They share 50% of their DNA, and double cousins share about 25% of their DNA.

Double cousins share the same amount of DNA that is shared with a grandparent, a half-sibling or an aunt or uncle. And they transfer this genetic exactness to their offspring: children of double first cousins are double second cousins, and so on. Finally, when identical twins reproduce with siblings their offspring are more related than half-siblings but less related than full siblings. They share between 25% and 50% of their DNA.

How Much DNA Twin Cousins Share?

As mentioned above that double cousin may be genetically siblings if their parents are identical twins. DNA test studies 642,824 genetic markers on each DNA sample of yours and anybody else you want to test against, and this will give you a pretty good idea of how similar and how different your and your double cousins are. The exact degree of relationship is discovered in the children of identical twins by genetic filiations through CRI Paternity. CRI Genetics digs into your past to tell you about your lineage, your ancestry, and your DNA specifics. CRI Paternity focuses on filiations with other members of your family and helps to build and interpret your tree.
