- Members of two separate species mate and produce hybrid offspring that fail to thrive in the environment. The hybrid genotypes do not suit the hybrid organism for survival using any given niche. Eventually, the hybrid genotypes disappear from the environment. This would be due to: A. hybrid inviability B. hybrid sterility C. gametic incompatibility D. pre-zygotic isolation E. infra-gametic disruptionarrow_forwardAllopatric, but not sympatric, speciation requiresa. reproductive isolation.b. geographic isolation.c. spontaneous differences in males and females.d. prior hybridization.e. rapid rate of mutation.arrow_forwardWhich of the following is an example of postzygotic reproductive isolation?a. Sperm of species A dies in the oviduct of species B before fertilization can take place.b. Hybrid zygotes between species A and B are spontaneously aborted early indevelopment.c. The mating seasons of species A and B do not overlap.d. Males of species A are not attracted to the pheromones produced by the females ofspecies B.arrow_forward
- Many species of birds choose their mates based on how brightly colored they are. If feather color is heritable, how would this violate the assumptions required for a population to be in Hardy-Weinberg equillibrium? HW equilibrium would cause mutations in such a species. A. This is a founder effect В. This is a bottleneck effect C. OD. Mating is non-random. Alleles for brightly colored phenotypes might become more common in the species and allele frequency would change.arrow_forwardOptions are a. Hybrid offspring. b. Speciation c. Adaptive radiation. d. Mechanical isolation.arrow_forwardMigration of individuals from a mainland population to a unique island population will result in… a. homogenization of allele frequencies between the two populations. b. isolation and bottleneck effect. c. increased homozygosity in both populations. d. increased population differentiation between the two populations.arrow_forward

Examining how populations lead to new lineages that arise based on alterations to allelic frequency and gametic exchange of new alleles is investigating ________________ a) macroevolution b) microevolution c) community ecology d) ecological species concept 2.

You find four populations with different paw colors (shown below) and note their mating habits and hybridization tendencies. Which of the following describes your findings correctly? A The different populations of Red Fox are affected by temporal isolation. B The offspring in the hybrid zones are affected by hybrid inviability. C The fox populations can be considered a ring species. D The fox populations can be considered an adaptive radiation. E The fox populations are affected by vicariance isolation.

- 1. Sea urchins are broadcast spawners that release clouds of sperm/eggs into the water column. However, the ability to successfully fertilize the egg by the sperm is restricted to very specific gametic proteins that inhibit cross species fertilization. This is an example of a a. Post zygotic barrier b.Habitat isolation c.Mechanical isolation d.Pre zygotic barrier e.Hybrid breakdownarrow_forwardThe biological species concept is based on the assumption that species are reproductively isolated and do not share genes. And yet a number of organisms that are considered different species hybridize (mate and exchange genes). Hybridization between different species is more common in plants than in animals. Propose some possible reasons for this difference.arrow_forwarda) How many of the gene trees do you expect to look like the species tree? b) You observe three gene trees in which species X and Z are the closest relatives and seven gene trees where X and Y are the closest relatives. What can you conclude from these data?
