Question

If an organism with 64 chromosomes mates with a closely related organism with 62 chromosomes, the most likely result will be _ sterile offspring due to hybrid sterility sterile offspring due to hybrid in viability many unhealthy offspring due to hybrid in viability no offspring due to hybrid sterility many unhealthy offspring due to hybrid breakdown Which avenue of research is least likely to reveal whether asexual organisms form species? looking into previously undiscovered types of bacteria hybridizing polyploidy plants exploring various niches in which different populations reside performing genomic research analyzing whether a cluster of bacteria constitutes a species

Explanation / Answer

1. b. sterile offspring due to hybrid inviability

Explanation: Mating between interspecific hybrids results in sterile hybrids due to the different number of chromosomes in the two species. Viable gametes are not produced by the hybrids as proper pairing and segregation of chromosomes cannot take place.
