Questions and Answers
What does the R allele encode?
What does the R allele encode?
- Stay green enzyme (Sgr)
- Chlorophyll
- Starch branching enzyme (Sbe1) (correct)
- Sucrose
What is the result of the r allele not making Sbe1?
What is the result of the r allele not making Sbe1?
- Chlorophyll is not broken down and the peas remain green
- Sucrose and unbranched starch build up, leading to wrinkled peas (correct)
- Sgr helps break down chlorophyll
- Starch branching enzyme (Sbe1) is overproduced
