Could have been a good textbook if it didn't suffer from a poor editing job throughout. Worse, you'd think that a book about genetics could - of all things - get the genetics of its cover animal right; it makes for a bad first impression. The authors write about how they chose to display an albino male green peafowl, Pavo muticus, on the cover as representative of albinism, "an iconic genetic phenotype now known to occur in many different organisms." Except that this bird isn't an albino individual, and it isn't even Pavo muticus - it's a white mutation of the Indian/blue peafowl, Pavo cristatus. The blue eyes - not red or pink - are a dead giveaway that it's not albino (as any geneticist worth their salt should be able to tell you!), and the fact that the authors don't even identify the right species casts doubt on the trustworthiness of any further information this book will try to pass off to you as scientific truth. It could have been a perfect moment (for a genetics textbook - again, of all things!) to talk about the difference between leucism (reduction of pigment, which is what the peafowl on the cover is actually an example of) and albinism (complete lack of pigment), in that not all organisms that look albino truly are albino. But, sadly, this moment gets lost in a pile of misinformation.
