With the exception of identical twins siblings who have the same two biological parents are likely to look similar but not identical to each other because they have?

Different combinations of genes inherited from their parents, leading to variations in physical traits like height, eye color, and facial features. This genetic diversity results in siblings having similarities in appearance but not being identical to each other.


Why are siblings not genetically identical?

Siblings are not genetically identical because they inherit different combinations of genes from their parents during fertilization. While siblings share approximately 50% of their DNA, the specific genes and variations inherited can be different due to the random assortment and recombination of genetic material during meiosis. This genetic variation leads to differences in physical traits and predispositions among siblings.


Why do siblings have similar physical characteristics?

Siblings look-a-like because they all have the same parents. Siblings don't look identical to their parents, they have variation in their characteristics. The same thing happens with plants and other organisms. Unless you have an identical twin. If you have an identical twin, you both have the exact same characteristics. The cell of identical twins makes an exact same copy with the cell. The process is called 'Embryo'.


If identical twins marry non related men are their children half siblings?

Yes, the children of identical twins married to non-related men are genetically half-siblings. This is because the twins share 100% of their genes, so their offspring would share 50% of their genetic material, making them half-siblings.


If identical twins marry identical twins could at least some of their kids look like twins having similar fingerprints?

They may look alike, but they will never have the same fingerprints, because fingerprints are created by differences of thickness in the dermal layer. It is independent of genetics, therefore, twins will never have identical fingerprints and any similarities between twins fingerprints would merely be coincidental.

Were all of Wilma Rudolph's siblings biological?

Yes, but some of them were half-siblings because her father married twice.


How are the Children of two sets of identical twin related?

Children of two sets of identical twins are genetic siblings, meaning they share the same genetic makeup as full siblings. This is because both sets of identical twins share the same DNA and pass on similar genetic material to their children. Thus, genetically, the children are as closely related as full siblings.


Non-identical twins can be both boys both girls or boy and girl why?

because fraternal twins (non-identical) are just like any other siblings. Their genders have no connection with each other.

Can biological siblings get married if one was adopted and has a different surname on their birth certificate?

yes and no. Yes because you see, in the UK (I'm not sure about in America) you can legally marry an adopted sibling.But.....If one sibling is adopted then they are not biological siblings. This is because they would have different biological (birth) parents, so the adopted child would be that... adopted.So to cut a long story short, if you are in the UK yesTo cut it short NO you cannot marry a biological sibiling adopted or not, that is incest.

Do half-siblings with the same father share any genetic similarities?

Yes, half-siblings with the same father share genetic similarities because they inherit half of their genetic material from the same biological father.


What are the genetic similarities and differences between half siblings?

Half siblings share one biological parent, which means they have a genetic similarity of about 25. This is because they inherit half of their genetic material from the shared parent. However, they also have genetic differences due to inheriting different genetic material from their other biological parent.


Identical siblings have exacly the same DNA why arn't they clones of one another?

Because the process of cloning requires taking an individuals DNA and putting it into a cell (in the case of a human an egg) and getting the egg to grow and reproduce that human that the DNA came from. Identical twins are genetic duplicates, but in the strict interpretation of the word "cloning" they are NOT clones because they were developed from one fertilized egg.


Why are enantiomers of biological interest?

Mainly because enantiomers have identical physical and chemical properties. However, the difference between two enantiomers can have tremendous impact, especially in biological systems, because many important biological molecules are chiral.
