Elected moderator on Unix & Linux. Feel free to @ping me in chat if there's anything I can help you with.

I am a computational biologist with a background in biology, not computers. My PhD work was on gene prediction and comparative genomics but my current research is in systems biology, specifically protein-protein interaction networks.

comment is it possible to completely reconstruct a family tree by DNA comparison alone?
@har-wradim re not completely stochastic: no it's not, that's why I said largely. As for choosing the right genome from a set, absolutely, that's a completely different proposition. However, in the OP we have to choose between siblings or mother/daughter so we don't have a set to choose from, we need to decide which hypothesis fits the data. That's what I don't think is possible but this is way out of my field so I don't pretend to know.

@har-wradim how can it be modeled? It is a largely stochastic process so I don't see how you could infer my parent's genomes from mine.

comment is it possible to completely reconstruct a family tree by DNA comparison alone?
Not confident enough to post an answer but I very much doubt it. There is a large element of randomness involved, I am not simply a mixture of my parent's DNA. Processes like chromosomal crossover ensure that a significant part of my genome is original so to speak. Therefore I doubt you can reconstruct a genealogy from this information.

Wow, the site is getting bigger, we actually already have a question about this insect (or a very close cousin), voting to close as a duplicate.

comment Do humans have enough biological differences to be grouped into races or subspecies?
While I see your point about there being races, I very much doubt you'll be able to support the use of the term as it tends to be used today. With the criteria you state, the Scots and the English would be different races, for example. If we take variations in vocalizations and geography as indications of race, each country will represent a race of its own. So while your argument does indeed support the existence of human races, it does not support the idea that those races are defined by color alone.

comment Evolutionary conservativeness
This is such a crappy question (not yours @biogirl, your teacher's). You cannot answer this question without actually checking the sequences. For example, the cell can survive without H1, OK, but H1 cannot function without it's structure since it's function is very dependent upon the structure. Therefore, it would not surprise me if it were exceedingly conserved. The question is an example of a lazy teacher, all you can offer is conjecture.

comment What does it mean when it's said so-and-so died a natural death?
This question appears to be off-topic because it is about and English idiom, not biology.

comment What does it mean when it's said so-and-so died a natural death?
This is not really a question about biology but about the English language and what is meant by a particular idiom. "Natural death" is not a biological term, it is a popular expression. Voting to close.

comment Why do farts stink, but perfume does not?
There are loads of "natural" things that smell good: flowers, food, your lover, your offspring, babies in general (at least to some people anyway), wood...

comment Is it possible for a human and another ape species to reproduce?
@ChinmayKanchi is it actually impossible or will it just lead to deformed offspring? Would an egg be fertilized and then die during development or is fertilization itself impossible?

comment Do humans have enough biological differences to be grouped into races or subspecies?
@Herman don't. You should edit your question in response to the answers you get. Your Q should always reflect what you are actually asking. I will look into this in more detail and update as soon as I get the chance.
