During an investigation, two German shepherds with long hair were each bred with a German shepherd with short hair in a fırst-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? Select the three correct answers. O Is hair length in German shepherds a dominant or recessive trait? O 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? O Is long hair in German shepherds an inherited trait? O What percentage of offspring in the second generation of German shepherds are homozygous for the recessive hair-length trait?
