What is the molecular explanation for the wrinkled peas in Mendel's experiment?
What is the molecular explanation for the wrinkled peas in Mendel's experiment?
- The R allele encodes Stay green enzyme (Sgr), while the r allele does not produce Sgr, causing wrinkled peas.
- The R allele produces sucrose, while the r allele produces unbranched starch, resulting in wrinkled peas.
- The R allele produces excess water, while the r allele leads to loss of water, resulting in wrinkled peas.
- The R allele encodes Starch branching enzyme (Sbe1), while the r allele does not produce Sbe1, leading to sucrose and unbranched starch buildup. (correct)
What does the Y allele encode in Mendel's pea experiment?
What does the Y allele encode in Mendel's pea experiment?
- The Y allele encodes Stay green enzyme (Sgr). (correct)
- The Y allele encodes chlorophyll.
- The Y allele encodes sucrose.
- The Y allele encodes Starch branching enzyme (Sbe1).
What happens when the r allele is present in Mendel's pea experiment?
What happens when the r allele is present in Mendel's pea experiment?
- Excess water enters young seeds, leading to loss of water as seeds mature.
- Sucrose and unbranched starch build up, leading to wrinkled peas. (correct)
- Chlorophyll is broken down, resulting in green peas.
- Ostomotic pressure is impaired, causing wrinkled peas.
