Question

In four-o’clock flowers red petals are incompletely dominant over white petals, producing pink petal flowers in the heterozygous stage. What would be the probability of having white offspring if two pink flowered plants were crossed?

Answer 1

Answer:

One in four offspring (1/4)

Explanation:

A pink flower is heterozygous, let's assume As.

Thus crossing two heterozygous, the result will be;

Aa x Aa

AA, Aa, Aa, aa.

The phenotypic result will be , one red petal, two pink petal and one white petal
