Example Question #21 : Understanding Dominant/Recessive
The eye color brown is superior to blue. Linda has brown eyes and marries someone with blue eyes. Linda's father has blue eyes and her mother is homozygous dominant. What is the percent chance of Linda's children having blue eyes?
Possible Answers:
0.75
0.50
0.25
1.0
Correct answer:
0.50
Explanation:
Linda's mother has brown eyes: BB
Linda's father has blue eyes: bb
Using the pedigree (BB x bb), Linda has to be Bb (100%). Linda is marrying someone with blue eyes (bb). Doing the pedigree of Linda (Bb) and her partner (bb) gives you 0.50 Bb (brown eyes) and 0.50 bb (blue eyes).
