Stripeless Poem by Ima Ryma

Most zebras have stripes black and white,
But ev'ry now and then there be
A zebra that does not look right -
Is altered genetically.
"Pseudomelanism" is where
There's skin cell manifestation
Causing no stripes upon the hair.
This is a rare phenomenon.
Though looking odd the zebra is
Still accepted into the herd,
And goes about all zebra biz
Even though it's not stripely furred.

Often such a zebra has lots
Of black fur with white polka dots.
