Roulette red blood cells The Code of Life

If both the father and mother of a child have the blood type B, what possible blood types could the baby have? And, while we're at it, what are all the possible blood types for any combination of parents? Well, at least you're not asking for much! I've put all of the most likely possibilities for any pair of parents in a table at the end of the answer. As you can see, two B parents are most likely to have either a B or an O child. Now two B parents having a B child is easy to understand. But roulette red blood cells does the O come from?

To understand this, we need to remember three things about genetics:. There is one gene that determines the ABO part of blood type. This gene comes in three versions -- A, B, and O.

Each roulette red blood cells our two copies of this gene can roulette red blood cells different versions. Here are the six ways these three gene versions can be combined and what each person's blood type online casino no deposit bonus july 2013 be:.

This is where point 3 comes in. The blood type gene makes a protein that sits on the outside of our red blood cells. Most of this is pretty straightforward. Why not AO or BO? The A version makes a protein that is just a little bit different than the B version. But the O version makes no protein at all.

And it is the presence of the proteins that determines our blood type. Knowing this makes the blood types easier to understand. Someone who has an A and a B version of the blood type gene makes both A and B proteins. And so is AB blood type. But someone who has a B and an O version poker casino game york makes roulette red blood cells B protein.

They are B blood type but can pass the O onto their kids. So two B parents can make an O child if both parents are BO. By each of them passing down their O version. If mom passes her O and so does dad, then the child will be OO which is O roulette red blood cells blood. A quick way to figure this out is using one of those awful Punnett squares from school.

The way a Punnett square works is one parent's two gene versions go on top and the other parents goes down the side. Here is an example with two BO parents:. To figure out the possibilities and the chances for each, you just match up the squares like this:. Note that genetically, not all of the B blood type kids are the same. The BB child roulette red blood cells only pass down the B version of the gene.

The BO child can pass on their O gene version. As I said, the blood tests used to determine blood type look at the proteins made and not the DNA. What this means is we can't tell a BO from a BB with these tests. You could with a DNA test but these aren't roulette red blood cells given. The Rh- gene version is like O in that it doesn't make any protein. There you have it. As promised, here is the roulette red blood cells showing what each combination of parents is here to have.

Well, one more thing before getting to the table. I want to emphasize that there are exceptions to these rules. I have put links at the bottom of this page to three blood type questions we've answered that explore some of roulette red blood cells ways to end up with a blood type that goes against the rules.

So if the table says you can't have the blood type that you have, don't jump to any conclusions! There are documented examples where these rules are broken. It is roulette red blood cells proteins on the outside of что joker wild casino Кажется cells that determines blood type.

Roulette red blood cells

It sounds like you are already well aware of the fact that every давал sac de voyage roulette pas cher Вот in roulette red blood cells body has the same set of genes. This is because all of the cells in our bodies start from a single fertilized egg. Roulette red blood cells first cell divided over and over again until a new baby was made.

And yet, all cells roulette red blood cells obviously not the same. It is easy to see that the cells in our heart, for instance, work very differently from the cells in our eyes. The same is true for our skin and our liver cells. Or our brain and muscle cells. Or any of the other or so different cell types. These cells are different because they use the same set of genes differently.

So even though each of jeu avatar en ligne cells has the same 20, or so genes, each cell can select which ones it wants to "turn on" and which ones it wants to roulette red blood cells "turned off". It might help to think about our set of genes as a cookbook and each of our cell types as a different cook.

So the breakfast cook focuses only on breakfast recipes and the lunch chef only on lunch ones. Just like our heart cells focus on heart genes and our eye cells on eye genes. Of course our genes aren't recipes for blueberry pancakes or minestrone soup. Instead, they are actually recipes for proteins. Genes are recipes that provide instructions that make us who we are. They determine what we look like and help our body to grow and function properly.

Just like a chef reads a recipe to make a dish, cells read a gene to make a protein. Each gene makes a specific protein that does a specific job. So one protein might let us tell red from green and another one might be part of the system to make a heart beat. And so on for all 20, of our genes. Cells need to make thousands of different proteins in the right amounts, at the right time, and in the right place in order to work properly.

Again this is like a chef. The chef needs to use the right recipes in the right amounts at the right time to make a meal work. First the appetizers, then the main course, and finally the dessert--all to feed the right number of people. It would obviously be a mess if the chef served everything all at once in a big bucket.

Same thing with a cell. Who wants their heart to tell red from green? Or their roulette red blood cells to pump? Not only would this be a bit creepy, but it could be bad for you. Your body would be wasting energy making proteins in places where those proteins aren't needed. And it could be downright dangerous!

For example, early on our cells need to divide and divide roulette red blood cells we can grow from one to trillions of cells. All of our cells have the growth genes churning our proteins to make the cells keep dividing. But when we are done growing, we don't want our cells to keep dividing. These genes stop making proteins and cells stop dividing so much. If the cells didn't roulette red blood cells growing, this growth would cause cancer.

So luxor casino everything is working OK, each cell type only reads the genes it needs. That way it only makes the proteins it needs too.

That is how cell types can be so different even though they have the same set of genes. The set see more genes we have has the instructions for everything about us. Each cell type just picks and chooses the recipes it wants to use. Kim Vande Wydeven, Stanford University. Since we start out as one cell, all our cells have the same DNA.
