Question

which family members have red - green color blindness? sam, tim, bella, and joshua lisa and monica ben, jenny, mike, carol, katie, and chris sam, joshua, and tim

Explanation:

In the pedigree chart, the red - colored (or affected - colored) symbols represent individuals with red - green color blindness. Sam, Tim, Bella, and Joshua are marked with the affected symbol (red - colored in the context of the chart). Lisa and Monica are carriers (half - colored), Ben, Jenny, Mike, Carol, Katie, and Chris are either normal (uncolored for males with normal genotype \(X^{B}Y\) or for females with normal genotypes) or their full status as non - affected is clear from the chart. Sam, Joshua, and Tim miss some of the affected individuals (Bella is also affected).

Answer:

Sam, Tim, Bella, and Joshua
