2. A nursery worker transfers pollen from a red four o'clock flower to a white four o clock flower.
The resulting seeds produce plants with pink flowers. What can you infer about the inheritance of
flower color in four o'clock plants? What would you expect to happen if you crossed one of the pink
flowers with a red four o'clock flower? Why?

It could inferred that mutation occur which led to sudden change and gives rise to pink flowers instead of either red or white

What would you expect to happen if you crossed one of the pink

flowers with a red four o'clock flower?

When red flower is crossed with the pink flower, the one with dominant gene will be more than the other as a result of dominance gene it posses

Why?

Explanation:

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
