The correct answer is:
A. Dominant
In this scenario, several red tulips were cross-pollinated with the pollen of an orange tulip, resulting in 526 red tulip buds and 120 orange tulip buds. Based on these results, the trait for orange tulips is most likely dominant.
In genetics, dominant traits are expressed when at least one copy of the dominant allele is present. This means that if the orange tulip trait was recessive, we would expect fewer orange tulip buds since it would require both parents to contribute the recessive allele for the trait to be expressed.
However, since 120 orange tulip buds were produced, it suggests that the orange tulip trait is dominant. This means that even with just one copy of the dominant allele, the orange color is expressed in the tulip buds.
Therefore, the correct answer is A. Dominant.
