WebAfter the crossover, one of the chromosomes will have a Huntington allele with fewer CAGs than before. This is the “contracted allele ” due to the contraction of the number of CAGs. The other chromosome will have a Huntington allele with more CAGs than before. This expansion results in the “expanded allele .”. WebHuntington's disease is caused by what kind of mutation?
