From a large scale screen of many plants of Collinsia grandiflora,a plant w/ 3 cotyledons was discovered (normally there are 2cotyledons) This plant was crossed w/ a normal pure-breeding w/wild type plant, and 600 seed from this cross were planted. Therewere 298 plants w/ 2 cotyledons , and 302 w/ 3 cotyledons. What canbe deduced about the inheritance of 3 cotyledons? Invent genesymbols as part of the explanation?

A) Define allele symbol.
B)Provide the genotype for wild-type plant:
