The child would have either the blood group A, B or AB. The rhesus factor may be positive or negative in the child.
See, the blood groups are determined by what alleles each DNA strand carries in a person. The alleles are A, O, and B. These may be in combination with each other … Read more

Yes. Type O blood is caused by a very common recessive gene — there is a good chance that both parents carry said gene. If they do, there is a 25% chance of the child having type O blood. As for the Rh antigen (positive vs. negative), the gene that creates that protein is dominant … Read more

From my understanding (as a biology professor, not a medical doctor), this should not pose a problem. Problems can arise when the mother is a negative blood type. Here's why: Negative blood types are lacking a certain protein that positive blood types have. If a woman has a negative blood type (no protein) and she … Read more

About all I can say here is that it's illegal to post pictures of someone on the Internet without their consent.  Not that people don't do it all the time, and it's basically impossible to know if someone has or not.  Flickr, Zooomr, and Pixsy are probably the most likely places he would do it … Read more

High school biology makes it seem like genes and eye color are straight forward....however, this site (www.thetech.org) begs to differ, and it is up to you to decide if you can believe this or not:   two blue-eyed parents can produce green or brown-eyed children. Eye color is not the simpleRead more

It is possible, but very rare.

The most likely cause of such a thing would be a form of albinism, though it is also possible, if both parents carried such recessive traits, for them to all appear in the child. However, the odds of a child getting only recessive appearance genes and as such looking entirely … Read more

Short answer: Yes.

Long answer:

Blood types work on a fairly simple dominant/recessive system — as far as ABO types are concerned, A and B are codominant (a person with one type A gene and one type B gene will have type AB blood) and O is recessive; the Rh marker is also caused by a dominant … Read more

As of right now there is no cure for herpes. However, there are many treatments which can lessen the frequency and severity of outbreaks. Talk to your doctor to find out what your best option is.

If you think, but are not certain, that you or your partner has HIV, then you should get tested ASAP, before having sex with anyone, regardless of whether or not you're using a condom.

If you know for sure that one of you is infected, then you/they should be under a doctor's care for it. Find … Read more

The only time you should have sex without a condom is if you are both 100 per cent certain that there is going to be no chance of either of you transmitting a sexually transmitted disease. If you are talking about using a condom to prevent pregnancy, then it is unlikely for a woman to … Read more

You don't.

You do not ever coerce someone into having sex, whether they're a virgin or they've slept with literally everyone you know but you, whether you've been dating them for three hours or three years, or even if you are married to them. That is rape.

Unless she has expressed to you explicitly that … Read more

There are two reasons for the taboo against incest.

One is increased risk of birth defects and genetic diseases, if two close relatives do choose to have children. However, this is commonly misunderstood and exaggerated, so let's talk about genetics for a second.

Most traits are caused by looking at two or more genes and expressing the … Read more

Sadly, this is a very common situation. School is stressful in the current generation. The average high school student today has the same anxiety level as the average patient in a psychiatric hospital back in the 1950s. 25% of teenagers have a diagnosable anxiety disorder. It's pretty awful.

So, the absolute best thing you can do … Read more

Yes and no — it's only possible in certain very unusual circumstances. I assume your concern is with a vaginal muscle spasm constricting the penis and causing it to become trapped — though such muscle spasms can occur and make separation difficult, it shouldn't be impossible.

They should do whatever makes them both most comfortable. It makes no physical difference whatsoever, therefore all that matters is both people's comfort levels.

However, I strongly recommend for people to be more open to the idea of a woman taking the lead, for one reason and one reason alone: When a heterosexual man is not … Read more

The common answer people give here — that it's either for depression or attention — is half true and half not.

Yes, self-harm is often a coping mechanism for emotional distress. Yes, it is often very visible. Yes, there are individuals who use that visibility to seek attention. However, what is misleading about this wording is … Read more
