meiome and genome

I thought eukaryote genetic inheritance came simply from the adding together of (recombinant) haploid chromosomes in the new zygote. But there is a lot of RNA involved? A crowd of unique proteins and mRNA in addition to the chromosomes in the gamete? See this: It is also noteworthy that during meios...

If you were able to isolate something like that and actually grow it, the simplest thing is to sequence genome and I don't doubt that companies that will send rockets to other stars/planets will have enough money for some small sequencer. Not to mention ...

The smoking gun of the debate: ring species. do they exist?

How ring species proof of macro-evolution? My argument is you can go from single organism with "full genome" (say wolf) to a range of diverse "mutants" (over 300 dog breeds that lost various genes) in relatively short time. Going in the opposite direction ...

cell specific markers

... of any two human individuals is said to be identical – but the 0.1% that is different accounts for a total of 3 million “letters” of the human genome. There are thought to be several tens of thousands coding genes in the human genome, thus it is possible that every single coding gene between ...
