- AKS 8a, DOK 2) Some scientist hypothesize that genetically engineering salmon to increase their size and the rate of growth can help meet human demands for protein. Which of these questions addresses the biggest concern scientist should research before releasing the genetically engineered salmon to the wild?arrow_forwardQ1: If all genes are composed of just four nucleotides, how can different genes carry different types of information? Q2: Would you expect to see more variation in the sequence of DNA bases between two members of the same species (such as humans) or between two individuals of different species (for example, humans and chickens)? Explain your reasoning. Q3: Do different alleles of a gene have the same DNA sequence or different DNA sequences?arrow_forward24arrow_forward
- S Warm up Wednesd.. omal Mutations ANALYZE Many people with balanced translocation mutations are not aware they have them until they try to have children. How is this possible? Select all correct answers. A. The person still has a full set of genes. B. There is no change in people's DNA until after they have children. C. Children inherit one chromosome from each parent, so they may not receive a full set of genes. O D. Cells easily repair these types of mutations, so they should not cause health issues unless repair mechanisms are not functioning properly.

You suspect there is selection pressure on the color of the flower: bees seem to cluster around the red flowers more often than the blue flowers. In a separate experiment, you discover blue flower color is dominant to red flower color. In a field, you count 600 blue flowers and 200 red flowers. What would you expect the genetic structure of the flowers to be?arrow_forward
