When multiple different alleles for a gene are present in a species's population it is called polymorphic. Most different alleles are functionally equivalent, however some alleles can give rise to different phenotypic traits. A gene's most common allele is called the wild type, and rare alleles are called mutants.
Combee will evolve into Vespiqueen at level 21, but only if it is female. Male Combee do not evolve. There is a 1/8 chance of a wild Combee being female. This is really rare iâ¦n HG and SS because Combee are a rare spawn period. 4 people found this useful.
Each Pokemon is different and not all evolve because they have reached a specific level (some evolve due to high friendship, being traded, getting an item used on them, etc.). â¦ Some Pokemon that evolve through level will evolve between levels 10 and 20, and some may not have their first evolution until the late 30s. Also, not all Pokemon evolve. If you want a very accurate, satisfying answer, you will need to ask about a specific Pokemon.
