The mechanism that causes a gene to move from one linkage group to another is called
inversion
duplication
translocation
crossingover.
Some individuals with blood group -$A$ may inherit the genes for blonde hair, while other individuals with blood group -$A$ may the gene for brown hair. This can be best explained by the principle of
Which phenomena leads to the variation in $DNA$
In a cross between white-flowered parents, $F_1$ progeny was uniformly purple-flowered. The $F_2$ progeny showed a phenotypic ratio $9 : 7$ between purple-flowered and white-flowered plants. The above result indicates that the flower colour is controlled by
