Which statement about analogies is correct? a. They occur only as errors. b. They are synonymous with homologous traits. c. They are derived by similar environmental constraints. d. They are a form of mutation.
What is the difference between a gene and an allele?
a.
A gene is a form of a trait, and alleles make up genes.
b.
A gene is a sequence of bases in a DNA molecule, and an allele is an alternative version of a gene that codes for the same feature.
c.
A gene is a sequence of bases in a DNA molecule, and an allele is an alternative version of a gene that codes for a different, but related, feature.
d.
A gene describes a chromosome, and an allele describes an exact location of a gene on a chromosome.
e.
An allele and a gene are the same thing.

A. they result from genetic and developmental similarities. B. they are epigenetic effects. C. they are derived from a common ancestor D. they result from convergent evolution E. they result because the environmental conditions of the ancestors were similar.arrow_forwardAccording to "The Complex Evolution of Homo sapiens", what is the significance of the L3 gene and who was the L3 woman?

- A researcher compares several species of maple tree by examining the amino acid sequence of a protein. The researcher discovers that the amino acid sequence differs in three locations depending on the species of tree. What can the researcher conclude based on this data? A. Maple trees are evolving rapidly. B. The different species have different morphological characteristics. C. The maple trees have been exposed to high levels of mutagens. D. The genetic makeup of the maple tree population has changed over time.arrow_forwardWhy did Galton modify the quincunx? a. Because the distribution of a trait (e.g., height) in offspring is more widespread than that of their parents. b. Because the distribution of a trait (e.g., height) in offspring has a higher mean relative to that of their parents. c. Because the distribution of a trait (e.g., height) in offspring is less widespread than that of their parents. d. Because the distribution of a trait (e.g., height) in offspring remains constant relative to that of their parents.arrow_forwardWhen closely related individuals mate with each other, or inbreed, the offspring are often not as fit as the offspring of two unrelated individuals. Why? a. Close relatives are genetically incompatible. b. The DNA of close relatives reacts negatively in the offspring. c. Inbreeding can bring together rare, deleterious mutations that lead to harmful phenotypes. d. Inbreeding causes normally silent alleles to be expressed.arrow_forward
- Before we understood genetics, the process of passing traits from parents to children was known as… Group of answer choices A. blending B. mixing C. fusion D. combining E. amalgamationarrow_forwardWhy is it that the allele coding for darker skin did not evolve to protect us from skin cancer? A. Darker skin did develop to protect us from skin cancer B. Because skin cancer usually develops before an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genes. C. Because skin cancer isn't harmful D. Because skin cancer usually develops after an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genesarrow_forwardThe text explains that selective breeding involves breeding animals or plants for specific desirable traits. For example, humans bred different types of dogs to accomplish certain jobs. Farmers breed chickens for having meat and laying a greater amount of eggs. Cattle are often selectively bred either for more meat or for more milk production. The text also notes that breeding animals for size and strength interferes with natural animal processes. Based on this information presented in the text, who benefits from the traits different animals are bred for? a) humans breeding the animals b) the animals being bred by the humans c) both the humans breeding the animals and the animals being bred by the humans d) animals not being bred by humansarrow_forward
