For a school project I need to find the number of chromosomes of an organism (specifically the adelie penguin, Pygoscelis adeliae). After several internet searches and a look through the encyclopedia at school, I am unable to find a definite answer to this question. Sources on the internet claim anything from 38 to 96 for diploid cells (with none of them citing a trustable study).
Is there any database that records the chromosome number for organisms?
Also, if this information is unavailable, what is the best way to estimate this value? On the Wikipedia article for number of chromosomes for various organisms, it listed the value for some birds, most of them in the 70-80 range. Is it safe then to assume that the number for penguins in general would be somewhere in this range?
