Answer 1

In snapdragons, petal color exhibits incomplete dominance. If we denote red petals as "RR" (homozygous red) and white petals as "WW" (homozygous white), their offspring will all be "RW" (heterozygous), which expresses as pink petals.

When you cross a red flower (RR) with a white flower (WW), the offspring will be:

• From RR (red) x WW (white), the offspring will be:
  • 100% RW (pink)

Thus, there will be 0% chance of getting a red flower from that cross. The correct answer is 0%.
