Therefore, the boy has hemophilia in the XhY genotype.
<span>Though both are unicellular, bacteria doesn’t possess a nucleus or cell organelles, except ribosomes, whereas amoebas possess a well-defined nucleus and all essential cell organelles.
Bacteria are prokaryotic. They do not have membrane-bound organelles. Their DNA is also not enclosed by an envelope. They do not possess a true nucleus.
Amoeba, however, is eukaryotic. Amoebas have a true nucleus, and it is enclosed by an envelope. The organelles are also membrane-bound.</span>
