The modal chromosome number of the goat ( Capra hircus ) is 60. The autosomes are acrocentric or telocentric, the X chromosome acrocentric, and the Y chromosome submetacentric. Quinacrine‐mustard staining and fluorescence microscopy make it possible to identify 28 out of 30 chromosome pairs. The X chromosome is one of the largest chromosomes, the Y chromosome the smallest. Homologous chromosomes vary considerably in length. The Q‐band pattern of the autosomes in goats and cattle seem to be identical. The X chromosomes in goats and cattle presumably contain equal amounts of DNA and the same number of Q‐bands, but the sequence of the latter are different.
