if an allele for a gene is fixed the frequency cannot change, which of the following statements is true? All members of the population are heterozygous There are at least 3 phenotypes related to that gene represented in the population The population is more genetically diverse because that allele is fixed None of the above
When a population is at Hardy-Weinberg equilibrium which one of the following is true? Group of answer choices Genotypic frequencies change generation after generation. One can calculate the recessive allele frequency directly from the number of homozygous recessive phenotypes seen. Individuals of the same genotype are most likely to mate. Allele frequencies change generation after generation.
There are 653 individuals in a population 104 of the rabbits in the said population have recessive floppy ears and 549 rabbits have dominant short ears. Use this information to calculate The dominant allele frequency the recessive allele frequency the homozygous dominant frequency the heterozygous frequency and the homozygous recessive frequency
Which of the following is a form of a heritable trait that enhances an individual’s fitness? Adaptation Lineage Fitness
Which of the following statements about genetic fitness and/or selection is false? Group of answer choices Individuals with low fitness have greater selection coefficients Fitness involves both relative viability and reproductive success Individuals with high fitness have greater selection coefficients Selection against recessive alleles tends to be slower overall than dominant alleles because of the survival in heterozygotes
Godfrey Hardy and Wilhelm Weinberg stated the principle of equilibrium to describe the genetic makeup of a population. The theory, also known as the Hardy-Weinberg principle of equilibrium, states that a population’s allele and genotype frequencies are inherently stable. Which of the following phenomena could disrupt this equilibrium? Mutations Selection pressure Migration All of the given choices
Which of these conditions should completely prevent the occurrence of natural selection in a population over time? Group of answer choices Variation between individuals is not heritable. The environment is changing at a relatively slow rate. The population lives in a habitat where there are no competing species present. The population size is large.
Which of these conditions should completely prevent the occurrence of natural selection in a population over time? Group of answer choices The population size is large All variation between individuals is due only to environmental factors The population lives in a habitat where there are no competing species present The environment is changing at a relatively slow rate
What does Hardy-Weinberg test? The robustness of a population Whether a population is evolving How many alleles are in the gene pool The proportion of fitness in the population
A new population is established using a mating pair. One of the mates expresses two dominant traits, and the other mate carries two recessive traits. After 25 years, the population is sampled again. Which one of the following results best indicates the two traits are linked? Group of answer choices 1. The number of individuals with two dominant traits is similar to the number of individuals with two recessive traits. 2. 50% of the population has two dominant traits or two recessive traits, and the other 50% have a mix of dominant and recessive traits. 3. 34% of the population is D/D, 35% of the population is R/R, 14% of the population is D/R, and 17% of the population is R/D 4. 23% of the population is D/D, 25% of the population is R/R, 26% of the population is R/D, and 26% of the population is D/R
In mice, the waltzing allele (w) that causes the mouse to run in circles due to an inner ear defect is recessive to the non-waltzing allele (W).In an ideal mouse population exhibiting Hardy–Weinberg equilibrium of 150 mice, 15% of the alleles are non-waltzing. What is the frequency of the recessive allele?Record your answer as a whole number percentage. Answer%
Which of the following terms are used to apply ONLY TO SELECTION, and never to just evolution. Choose all that apply. (1 or more are correct). founder effect fitness allele frequencies bottleneck effect selective advantage/disadvantage cost/benefit
