Multiple alleles is the in
which the same has more than
two alleles (in normal
mendelian the genehas only
two ). Obviously these alleles
combine pairs to form the .
In multiple alleles relative
among the alleles may . A typical
example of alleles is the
inheritance the ABO blood group
, in which there are alleles
(A, B or , or IA, IB and ). IA is
dominant over , which is recessive in
to the other IB . IA and IB
lack between themselves.
Another example the colour of rabbit
, conditioned by four different
(C, Cch, Ch and ). In this case the
relations are C> Cch Ch
> c (the > means “dominates
over”).
