Use the information and your knowledge of science to answer the question. A scientist crosses morning glory plants of different flower colors to determine how flower color is passed on to offspring. The results of three crosses are shown in the table. (Hint: You must determine which color is dominant using the chart to answer the question.) The scientist crosses an offspring from cross X with an offspring from cross Z. What are the expected results of this cross? https://learning.k12.com/content/enforced/433791-COF_ID122940/PastedImage_elye1hvnyqffiu5j9go8ufpzvkl4ry6w002.png?_&d2lSessionVal=092H9SyKGOcP3adKh9ywK7xHl A. 100% of plants with red flowers B. 100% of plants with purple flowers C. 50% of plants with red flowers, 50% of plants with purple flowers D. 75% of plants with purple flowers, 25% of plants with red flowers

During an investigation, two German shepherds with long hair were each bred with a German shepherd with short hair in a first-generation cross. The offspring from each first-generation cross were then bred to produce a second-generation cross. Which questions could be answered using the results of this investigation? Choose the three correct answers. Question 1 options: Is hair length in German shepherds a dominant or recessive trait? How often does the mutation for long hair randomly occur in German shepherds? How does the protein made by the gene for hair length differ among German shepherds? Is long hair in German shepherds an inherited trait? What percentage of offspring in the second generation of German shepherds are homozygous for the recessive hair-length trait?
