Question:
Is CriDuChat a dominant or recessive trait?
Replies:
There is a Chinese word, "mu" which among other things can be translated as
nothing, or neither...in this case, I choose neither. This syndrome is
caused by the deletion of part of chromosome five and therefore affects many
genes, mostly in unknown ways. The loss is considered "spontaneous", which
like a theory long ago called "spontaneous generation" is just a way to say
we don't know why it happens. The term dominant, as you know, refers to a
certain form of an allele...so you can see why your question has no answer
from the two choices you proposed.
