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?

i dont know the first one but the second one is both The dog will have short hair and carries the gene responsible for long hair The dog has two copies of the long-hair allele. The dog will have long hair and will always pass on a copy of the long hair allele to any offspring. i dont know the thrid one but the fourth one is a inherited trait and the last one is les than 25%
