parental definitions of chromosomes in heterozygous animals

Post by chrtam » Fri Mar 18, 2011 10:34 am


If you cross two heterozygous animals, is there an easy way to distuinguish chromosomes from one animal and the other in their heterozygous offspring to see if the mutation is paternal or maternal?

I guess there is not an easy way of doing that unless you have more than one characther both of which are inherited in genes that are on the same chromosomes. See

Or, if the given gene is an imprinted gene, its expression depends on its parantel origin. For example, Angelman syndrom/Prader-Willi syndrome are caused by the same genetic mutation; but their particular syndroms are different from each other and this difference is determined by parental origin of allele (related to epigenetics).
