Answer 1

Ken and Kendra share 50% of their genes. Lara an Lonnie share 100% of their genes.
The fraternal twins are just siblings that share the same womb. Each of them starts it's development as separate egg that is fertilized by a separate sperm, so they are no more similar than the other siblings.
The biological (identical) twins, on the other hand, come from the same fertilized egg, thus they share the same genes.

Answer 2

Answer:

The correct answer is 50; 50

Explanation:

Fraternal twins are born because of the fertilization of two ova during a single pregnancy. Fraternal twins can be of same-sex or different-sex according to the type of chromosome sperms carry which fertilize the two different eggs. Both fraternal twins share 50% of their genes just like other siblings.

Biological siblings are born from the same biological parents that means they also share 50% genes with each other. They are full brothers and sisters or full brothers or full sisters. They are also called full siblings.

Therefore both fraternal twins and biological siblings share 50 % of their so the correct answer is 50; 50.
