How do these work? i. Artificial selection ii. Natural Selection iii. Gene flow iv. Non-random mating

A farmer breeds sheep with the desired traits of disease resistance and tine wool. After several decades of breeding efforts, the farmer's flock is resistant to disease and produces fine wool. Which evolutionary mechanism is responsible for the changes in the gene pool of the farmer's flock? A:Sexual selection B:Artificial selection C:Natural selection D:Gene flow

In 1959 Daniel Yuh set up a long-term study of cataloging the blood types of a group of foragers in the Brazilian rainforest. In 1959 he found there were no individuals with blood type B. Three generations later, after this group had begun exchanging mating partners with another group, there were several members with blood type B. A-mutation B-natural selection C-gene flow D-genetic drift

Natural selection can edit the nucleotide sequence of an allele inside an individual. Question 8 a. False b. True

Student 1: Artificial selection is done on humans and this creates mutations . Student 2: Artificial selection has only recently been done by scientists. Student 3: Different breeds of cows have been created through artificial selection Which student do you agree with the most and why?

Dog breeders use selective breeding, also called artificial selection, to maintain a closed genetic lineage, and produce offspring with desirable traits. This violates which Hardy-Weinberg condition? a reproduction b no mutation c random mating d no natural selection

1. The majority of antibiotic use in the United States is for agriculture, primarily in livestock. Why is this a problem? 2. Given the fact that humans are the ones producing and distributing pesticides, why do we call the development of pesticide resistance natural selection rather than artificial selection?

Why is it that the evolution of skin color is considered a case of natural selection? Group of answer choices A- Because different alleles in skin color genes lead to differences in skin color   B- Because differences in skin color lead to differences in number of children in different environments   C- Both   D- Neither
