Question

Scientists studied two closely related species of flowering plants growing in the same region. They examined characteristics of the seeds and mature plants representing the F_1 offspring of crosses within species A. within species b. and between species A and B. The data suggest that in the future, hybrids will likely A. not persist past this Fi generation, because the hybrid F_1 generation is completely infertile. B. not persist for many more generations after F_1. because the hybrid F_1 generation has very low fertility. C. persist for many generations after F_1. because the hybrid F_1 generation will displace the purebred lineages. D. persist for many generations after F_1. because mating between species A and B produces viable offspring. E. persist for many generation after F_1. because positive selective pressures will favor the evolution of increased viability of hybrid seeds.

Explanation / Answer

D) hybrid will persist for many generations after F1 because mating between Species A and B produce viable offspring.

A is wrong because we don't know anything about F1 being fertile or non fertile.

B is wrong because F1 has low fertility is not mentioned anywhere.

C is wrong because parental lineages will not be displaced by the hybrids

E is wrong because over the generations positive pressure will not increase the viability of hybrids.
