- How did Darwin develop his theory of evolution? A. Experimentation. B. Observation. C. Both experimentation and observation. D. Statistical analysis.
- Evolution, viewed on a small scale, as it relates to changes in a single gene or allele frequency in a population over time is called a.macroevolutionb.speciation c.genetic evolution d.phenotypic evolution e.microevolution
- If a haploid cell divides by mitosis the resulting daughter cells will also be haploid.
- Peter and Rosemary Grant study natural selection in finches on the Galápagos Islands. They have hypothesized that dry condition produce larger seeds and may result in larger beaks in succeeding generations of finches. The figure below shows their data from 1976 and 1978. The y-axis is the number of birds measured and the x-axis is the beak depth. Do their data support their hypothesis and why? A. Yes; because there were more birds measured in 1978 after the drought, therefore they must have been able to get food and reproduce. B. Yes; because the average beak depth of birds in the population increased from 8.8mm in 1976 to 9.8mm in 1978. C. No; because even though more birds were measured in 1978, the beak size of the upper range was smaller. D. No; because in 1976, before the drought, the largest beak depth was still 11.3mm. E. No; more data would be necessary to show a support of their hypothesis.
- Sex-linked traits are located on autosomes.
- Hair color, eye color, and height are most likely caused by multiple alleles
- The term evolution is used to describe a. heritable changes in characteristics of a population from one generation to the next b. any change in an individual that can be observed c. changes in the number of individuals in a population due to matingd. the ability of an individual organism to pass on what it has learned, through experience, to the next generation\e.any change in an individual organism that occurs in somatic cells
