The basic chromosome number in
The somatic chromosomes in “diploid”
Multiple association occurs amongst the chromosomes of “diploid”
In “triploid” varieties of
Instead of giving a binomial frequency or the elimination of intermediate numbers, natural seedlings of “triploid” apples most frequently have numbers of chromosomes approximately to 2
Thus the pairing, morphology, and breeding results show, directly or indirectly, that the thirty-four chromosomes in the “diploid”
The number seventeen is therefore a secondary (unbalanced) basic number, and the derived series of polyploids (2
The establishment of a secondary basic number must mean (on the analogy of all experimental observations) a definite evolutionary step. It is therefore plausible that the

The inheritance of 13 genes in
These genes include: Three controlling morphological characters (B, I, D). Three controlling leaf colour (V, X, Y). Seven controlling flower colour, (1) plastids (P, Q), (2) anthocyanin (A, G, R, S, L).
There are two pairs of complementary genes, X, Y and P, Q.
The presence of A is necessary for the expression of the other genes for anthocyanin colour in the petals; G is epistatic to R; and minor modifiers of colour occur.
. No certain linkage has been found between any of the genes.
