• the size of the ventral ectodermal ridge of the tail (VER) is reduced to 69% of the normal size

embryo
• the notochord is increased in bulk not only in the distal growth zone (as in T heterozygotes) but in the whole tail, in the cloacal region and even more anteriorly in the lumbar region and has large lumina
• the notochord is present throughout the length of the tail, however it becomes incorporated into the neural tube throughout the tail and often the cloacal region
• the size of the ventral ectodermal ridge of the tail (VER) is reduced to 69% of the normal size
