Problem:

In unicorns, two autosomal loci interactto determine the tye of tail. One locus controls whether a tail is present a all; the allele for a tail (T)is dominant over the allele for tailess (t) . If a unicorn has a tail , then alleles at a second locus determines whether the tail is curly or straight . Farmer Baldridge from pink , OK has two unicorns with curlry tailes . when he crosses these two unicorns, 1\2 of the progeny has curly tails , 1\4 have straight tails and 1\4do not have a tail.

Required:

Question 1: Give the genotypes of the parens ad progeny in Farmer Baldrigdes cross .
Question 2: Explain how he obtained he 2:1:1 phenotypic ratio in this cross.

Please provide description of your answers.
