Textbook Question
Chapter 13, Problem 7LTB
The biological definition of “race” corresponds to all of the following except.
- the genealogical species concept;
- the idea that subgroups within the same species can be distinguished from each other by ancestry;
- there is a natural hierarchy of groups within a species from “lowest” to “highest” forms;
- it should be possible to identify races on the basis of shared allele frequencies among populations;
- races within a species are not reproductively isolated from each other.

- Indicate the order in which the following steps would take place to result in Parapatric Speciation [enter 1 for the first step, 2 for the second, etc; write only the number -- no words, no spaces] Something happens so that the environment is different in one part of the range relative to the other, even though the populations are still contiguous. As they adapt to their specific environments, the fitness of any hybrid formed is reduced. The populations adapt to their environment in the part of the range where they live. Interbreeding populations connected via gene flow occur across a range. Reproductive isolating mechanisms are selected for so that less fit hybrids are not formed. Two species now exist.arrow_forwardThe images below depict a female (left) and male (right) primate of the same species. Based on these images, would you agree that a high degree of sexual dimorphism is present? If so, what traits indicate this? Mark all that apply. Group of answer choices Yes, a high degree of sexual dimorphism. No sexual dimorphism - these would be considered an example of sexual monomorphism. Male has much larger canines. Male has a sagittal crest Male is much larger in overall sizearrow_forwardA certain population of Sistrurus milarius, there exists an allele “d" which has the frequency of 25%. This allele confers the ability to allow the organism to grow to lengths exceeding 3m. This population occurs in the northern 2/3 of Alabama. Out of a population of 80, find the following: # of individuals who are homozygous dominant # individuals who have the recessive diseasearrow_forward
- Which of the following is the definition of a gene pool? The combination of alleles that an individual organism possesses. All the alleles in an ecosystem. The total number of individuals in a population. All the alleles in a population of a particular species.arrow_forwardIndicate the order in which the following steps would take place to result in Sympatric Speciation [enter 1 for the first step, 2 for the second, etc; write only the number -- no words, no spaces] As they adapt to their specific environments, the fitness of any hybrid formed is reduced. Reproductive isolating mechanisms are selected for so that less fit hybrids are not formed. Two species now exist. Interbreeding populations connected via gene flow occur across a range. The populations in the new environment adapt to their particular circumstances while the remainder stay as they were. Something happens so that some members of the populations/species change their environment (shift hosts; have a genetic change like polyploidy or inversions), so that they are separated from the others even thought hey are living in the same area.arrow_forwardThere are 1024 individuals with the genotype GG, 512 individuals with a genotype Gg, and 64 individuals with the genotype gg.

- When taxonomists recognize subspecies, they are identifying: populations with restricted enough gene flow to develop some population-specific traits, but that can still interbreed with members of other such populations. None of the other answer options is correct. populations that are reproductively isolated from one another. populations with extremely restricted gene flow due to allopatric isolation. O populations that will inevitably become separate species as reproductive isolation is nearly complete.arrow_forwardWhich of the following are true about human variation? (Choose all that apply): Group of answer choices Genotype refers to how a person looks, through interaction of genes and environment. Siblings are more like each other, genetically, than they are to either of their parents. Usually, it is only identical twins (or sometimes triplets or other multiple births) who have identical DNA, and even so, there is still some phenotypic variation between them. You could have genes for being tall, but if your mother (or even grandmother) had poor nutrition during fetal gestation, you could be shorter than your genes allow. You can produce taller offspring by stretching and remembering to stand up as tall as you can.arrow_forwardThe Hardy–Weinberg principle states that allele and genotype frequencies remain constant from one generation to the next, as long as specific conditions are met.Choose Yes or No for the conditions that must be met from the provided statements below. Mutations are exponentially occurring. All members of the population breed. Everyone produces the same number of offspring. The population is infinitely large. There is no migration in or out of the population. No net mutations are occurring. Natural selection of beneficial traits is occurring. Natural selection is not occurring. All mating is completely random. Offspring are able to migrate out of the population.arrow_forward
