In dogs, there is a hereditary deafness caused by a recessive gene, "d." A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, so the owner knows his genotype is either DD or Dd. If the dog's genotype is Dd, the owner does not wish to use him for breeding so that the deafness ...Scientific Method.

Then you are prepared to pursue the outcome of each cross using the forked-line ...

If the genetic basis of a trait is known one can predict the outcomes of crosses. These are Punnett square method, forked line method and probability method. The ratios predicted from Mendel's law, apply to a new allele combination to each newly conceived of fspring i.e. 50% chance of inheriting the allele, no matter
