Question: Which one is a monoembryonic citrus genotype? (RJ ARO Horti 2022)
Options:
Grapefruit
Acid lime
Sweet orange
Pummelo
✅Explanation: Pummelo is a monoembryonic citrus genotype. This means that its seeds typically produce only one embryo, resulting in a single seedling per seed. This is in contrast to polyembryonic citrus varieties, which produce multiple embryos per seed, often resulting in a mix of genetically identical and diverse seedlings.
