| Dwarfism
At least three types in cattle:
snorter dwarfism: most common; short, blocky appearance; deformed bone growth in nasal passages causing difficult breathing;
long head dwarfism: small size but normal nasal passages;
compress dwarfism: extremely compressed body conformation with one compress allele and one normal gene; dwarf and death at or soon after birth with two compress alleles
Simple recessive (snorter dwarfism; long head dwarfism); incomplete dominance (compress dwarfism); environmental causes
