Calicos can be XXY, which may present male genitals but is intersexed and both male and female. The genes for color are coded on the X chromosome. That's why only females are calico.
All calicos have 2 X chromosomes. That means they are either female, or in rare cases intersexed XXY with male genitals. There are no strictly male calicos. It's literally and biologically impossible.
Every article you've posted and every article you will post says the same thing.
For a male cat to have a calico pattern, the feline has to have three sex chromosomes: two Xs and a Y. This phenomenon can happen in both humans and animals and is, in either case, known as Klinefelter syndrome.
Again, they may present with male genitals, but genetically they are both male and female. There are no male calico cats. It's literally impossible.
Call them whatever you want. Genetically they are male and female. This is simple biology, which is apparently much more complex than you seem to understand.
You probably want to get on writing some letters to…. Seemingly ALL journalists on the subject along with every veterinary based resource site on the subject and let them know that they’re wrong about something that only you are right about.
He’s right. You are just being really stubborn. The fact you think biological sex is simple is a big giveaway you don’t know what you are talking about. XXY is not considered intersex and never has been.
