In a particular species of plant, the colour of the flowers is determined by a single pair of alleles, where the dominant allele (A) gives rise to red flowers and the recessive allele (a) produces white flowers. A gardener crosses two heterozygous plants (Aa) and wants to predict the expected ratio of red and white flowers in the next generation. Taking into account Mendel's First Law on the segregation of alleles, what is the likelihood that a plant from this cross will have white flowers?

The probability of a plant resulting from this crossing having white flowers is 75%.

The probability of a plant resulting from this crossing having white flowers is 50%.

The probability of a plant resulting from this crossing having white flowers is 10%.

The probability of a plant resulting from this crossing having white flowers is 25%.

The probability of a plant resulting from this crossing having white flowers is 0%.
