Which of the following is not an example of a postzygotic barrier between different
species?
The hybrids created by interspecies crosses are usually infertile

Often times the embryo created through an interspecies cross fails to develop and dies
The hybrids created through interspecies crosses are generally very unhealthy

- Which of the following statements about sympatric speciation is correct? It is a process through which two populations can diverge and develop reproductive isolation while in two different geographic area. It is the most common mechanism for populations to form independent species. Postzygotic isolation is the main form of reproductive isolation for the sympatric speciation process. Genetic isolation through large scale chromosomal mutations, such as chromosome inversion or polyploidy, are more likely contributing to sympatric speciation. None of the abovearrow_forwardWhat are examples for gene flow? Select all that apply A distinct population of iguana drift to a new island that is already inhabited by members of the same species. A small population of humans colonizes a newly formed island. A fire drastically reduces the size of a white-tailed deer population. The remaining individuals spread out throughout the remaining forest. Wind blows pollen from one population of plants to another and cross-fertilization occurs. n An earthquake results in the formation of a canyon, splitting a population of toads apart.arrow_forwardWhich of the following are post-zygotic reproductive barriers?a. Different mating songs prevent mate recognitionb. Species A breeds in Spring, Species B breeds in summerc. Species A and B mate, but the embryos die before hatchingd. The gametes of species A aren’t compatible with the gametes of species Be. Species A and B can mate and produce healthy offspring, but the offspring are infertilearrow_forward
- Which of the following is true of a peacock's tail: It is a result of intersexual selection It is an example of sexual dimorphism in the species It is a result of intrasexual selection all of the abovearrow_forwardFrogs have external fertilization; however, the male frog will jump on the female and squeeze her to stimulate her release of her eggs. The males will jump on every female in sight regardless of the species. Females will only mate with the male frog that has the appropriate call for her species. If a male from another species clasps a female of the wrong species, she will issue a “release call” which causes the male to let go. what type of isolation mechanism is this and whyarrow_forwardWhat is an example of how migration causes changes in gene frequencies? Genetic material can become lost over time due to lack of reproduction when animals migrate. When animals migrate, their genes mutate on their own, changing the frequency that a gene allele shows up. When animals migrate, the mating becomes less random, causing inbreeding and, therefore, shifts in the proportion of alleles. Seeds of plants are carried to different locations and introduced to a new population, adding their own genetic material and, therefore, changing gene frequencies.arrow_forward
- Which of these outcomes are examples of reproductive isolation? Select all that apply. Individuals of different species are physically compatible and can engage in sex Hybrid individuals cannot produce offspring Hybrid individuals or their offspring have similar fitness to the original species Reproduction occurs at different times Mating occurs but fertilization does not occurarrow_forwardWhich of the following is not true for a critically endangered species? Expression of deleterious alleles and increased homozygosity increases mortality of young, and inbreeding depression leads to reduced offspring fitness The individuals of the species which have declined to low numbers are still a genetically open system Loss of some allele from the species causing loss of genetic diversity with consequent inability to respond rapidly to selection Reduction of population breeding ability due to increased relatedness through the action of incompatibility mechanisms in plants or behavioural difficulties in animalsarrow_forwardWhich of the following species would have the greatest chance of going extinct? a species with a slow reproduction rate and very little genetic variation living in a changing environment a species with a fast reproduction rate and lots of genetic variation living in a changing environment a species with a slow reproduction rate and very little genetic variation living in a stable environment a species with a fast reproduction rate and lots of genetic variation living in a stable environmentarrow_forward
- Which of the following is not a post-zygotic isolating mechanism? Group of answer choices zygote mortality hybrid sterility temporal isolation F2 fitnessarrow_forwardThe approximately 600 species of cichlids in East Africa’s Lake Victoria have largely resulted from sympatric speciation. The closely related cichlids species P. pundamilia and P. nyererei are thought to have arisen by sexual selection. Mate choice by females strongly favors males of their own species that have different body colors. In recent years, pollution has caused the water of Lake Victoria to become turbid in some areas. Hybrids of P. pundamilia and P. nyererei were produced and the gene pools of the two species have started to fuse, creating a new hybrid species. In this process, what are the conditions that led to the fusion of P. pundamilia and P. nyererei? A. Only the prezygotic reproductive barrier is not complete for the two species. B. Only the postzygotic reproductive barrier is not complete for the two species. C. Both the prezygotic and the postzygotic reproductive barriers are complete for the two species. D. Both the prezygotic and the postzygotic reproductive…arrow_forwardTwo populations of the same species of frogs have been separated by a mountain range for thousands of years. The females from one population are no longer attracted to the mating calls of the males from the other population. This is an example of which type of reproductive isolation mechanism?
