| 1) It is necessary to carry out an analyzing crossing. Cross a bull with a red horned cow – a recessive digomozygote.
2) If the resulting offspring are 100% black hornless, it means that the bull is a purebred (AABB), if the offspring is split, at least for one trait – the bull is not a purebred.
