Which feature is MOST important for defining a population? Individuals live together in the same place Individuals interbreed with equal probability Individuals are alive at the same time. Individuals are members of the same species. Individuals have similar cultural values.

Huntington’s Disease A population of people has a gene that determines whether they will developHuntington’s disease. The gene has two alleles, ”N” for normal allele and ”h” for the Huntington’s allele.According to the Hardy-Weinberg equilibrium, the frequency of the ”h” allele in the population is 0.005. Part AWhat is the frequency of the ”N” allele in the population?Part BWhat is the expected proportion of people in the population who are carriers of the Huntington’s disease?Part CWhat is the expected proportion of people in the population who are non-carriers of the Huntington’s disease?Part DWhat is the expected proportion of people in the population who will develop Huntington’s disease?

select all assumptions that are true about a population that is in hardy weinbirg equilibrium - random mating  - small population  -mutation rate is zero  - gene flow is occurring  -no natural selection

Which pair of terms most accurately describes the life history traits for a stable population of wolves? iteropparous; K-selected iteroparous; r-selected semelparous; K-selected semelparous; r-selected

Males of one mouse species are too small to mate with females of another species. This is an example of what kind of reproductive barrier?   Group of answer choices Hybrid Inviability Mechanical Isolation Behavioral Isolation Temporal Isolation Habitat Isolation

Voles of two different colors, brown and gray, live on the same island. Hawks find these voles to be their primary food source. The voles are distributed through grassy areas in the north of the island and across lava flows in the south part. Which of the following is predicted by natural selection? Hawks find the voles by movement so it won't matter. A vole population that starts as a random mixture will never adapt to the environment. Brown voles are good at hiding in the grass; gray voles are excellent at climbing over lava flows. Consequently, the vole distribution will reflect the ability of hawks to identify each of them in its natural environment. If they stay as a mixed population, they will remain mixed because the two varieties will not interbreed with each other. The hawk population will be skewed toward the north side of the island

In a population that is in Hardy-Weinberg equilibrium, the frequency of allele a = 0.3.  What is the percentage of the population that is heterozygous for this allele? Group of answer choices 40 42 3 21 9

In which population is evolution by natural selection most clearly demonstrated? Group of answer choices A virus sweeps through a population and makes everyone ill.  A virus sweeps through a population and kills 10% of infants. It is not clear why some die and some don't. A virus sweeps through a population and kills 20% of the population. It is not clear why some die and some don't. A virus sweeps through a population and permanently sterilizes the 10% of the population that has allele hx25c.

The frequency of the recessive allele (r) in a population is equal to 0.70. What percentage of the population is likely to have a homoygous dominant genotype? 9%, 42%, or 49%
