- When species arise as a result of changes in chromosome number that make them incompatible with the parental species, it is referred to as • hybrid reinforcement • hybrid speciation • homoploid hybrid speciation • polyploid hybrid speciation • pre-zygotic isolationa specie that have a derived trait, among others?What factors can support the long-term stability of a hybrid zone if theparent species live in different environments?
- A large plant arose in a natural population. Qualitatively, it looked just the same as the others, except much larger. Is it more likely to be an allopolyploidThere are two genetic loci determiningthe mating type, locus A with 288 alleles and locus B with 81 alleles.(2 points) List a cross of two Schizophyllum commune strains that could successfully mate and across that could not succeed.Successful cross:Unsuccessful crossUse two different colors to depict the unduplicated chromosomes of species C with larger chromosomes (2n = 8) and species D with slightly smaller chromosomes (2n =10), and of their F1 hybrid. Is the hybrid likely to befertile?
