Purple petal color in pea plants is dominant to white petal color. two heterozygous pea plants are crossed. what ratio of the offspring will have white petals? : express this in a percentage. %

The ratio of the offspring will have white petals is 1/4. Which means 25%  of the offspring will have white petals.

According To the Mendel's Law:

When two heterogygous parents cross,

Find the attachment for cross.

Hence, we can conclude that the ratio of the offspring will have white petals is 1/4. Which means 25%  of the offspring will have white petals.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
