Hello !! Cats that have a hair dappled orange, white and black, also known as turtle or calicut, are always females to genetic causes. In cats fact, the information for the synthesis of pigments black and orange are found in the same gene that is part of the chromosome X. Because it gets all the nuances, the alleles (i.e. genes in the corresponding position in the chromosome pair) must be present the two X chromosomes However, only females have two X chromosomes, while males have a genetic type XY (like humans). The absence of the second X chromosome in males causes a phenomenon called "X inactivation". A male can therefore be either black and white or orange and white, but not black, orange and white. There is only one case in which a male can be tricolor, and that is a subject with XXY genetic makeup, gene abnormalitytica called Klinefelter syndrome, which leads to infertility.
This is the scientific explanation, much more 'just when you see a cat with the robe in three colors are certain that it is female. From personal experience I am also more 'cuddly and clever
Ciao!!I gatti che hanno un pelo pezzato arancione, bianco e nero, detti anche tartaruga o calicut, sono sempre femmine per cause genetiche. Nei felini infatti, le informazioni per la sintesi dei pigmenti nero e arancione si trovano in uno stesso gene che fa parte del cromosoma X. Perché si manifestino tutte le sfumature, gli alleli (cioè geni in posizione corrispondente nella coppia di cromosomi) devono essere presenti sui due cromosomi X. Tuttavia, solo le femmine hanno due cromosomi X, mentre i maschi hanno un corredo genetico di tipo XY (come nell'uomo). L'assenza del secondo cromosoma X provoca nel maschio un fenomeno chiamato "inattivazione X". Un maschio dunque può essere o nero e bianco o arancio e bianco, ma non nero e arancio e bianco. C'è un unico caso in cui un maschio può essere tricolore, ed è quello di un soggetto con corredo genetico XXY, un'anomalia genetica chiamata sindrome di Klinefelter, che porta a sterilità.
Questa è la spiegazione scientifica , molto piu' semplicemente quando vedi un gatto col manto a tre colori stai certo che è femmina. Per esperienza personale sono anche le piu' coccolose e intelligenti

Sisi I have 3 cats and the female is actually the most shrewd despite his advanced age, and the story of the three-color just did not know; thanks for the interesting explanation. A greeting!! :-)
Lawrence Sisi di gatti ne ho 3 e la femmina è effettivamente la più scaltra nonostante l'età avanzata, e questa storia della tricromia proprio non la sapevo; grazie mille per l'interessante spiegazione. Un saluto!!
