Which of the following is not an example of cytoplasmic inheritance?

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

The phenomenon in which an allele of one gene suppresses the activity of an allele of another gene is known as

When two non-allelic genes are present together,they produce a new phenotype,but when they are separated,they do not show this effect. This is called:

In wheat,when a green plant was self-fertilized,the progeny had $209$ green seedlings and $14$ white seedlings. The above result indicates that:

Fruit colour in squash is an example of
