Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A pedigree chart shows two affected individuals for hemophilia, an X-linked trait. If they have a son and a daughter, what are the probabilities of each child being affected?

💡 Hint: Examine X chromosome contributions from both parents.

Challenge 2 Hard

Consider a population of snapdragons with red, white, and pink flowers. If a red flower (RR) is crossed with a pink flower (Rr), what will be the ratio of phenotypes among the offspring?

💡 Hint: Use Punnett squares to visualize allele combinations.
