The "Boutu" is a French imaginary animal, which has many strange characteristics. In this problem we will consider the following as true: the "Boutu" is diploid and its genetics obeys the rules of Mendel. Assume that the two genes involved assort independently. PART A) Two " Boutu" from two pure breeding lines are crossed. A "Boutu" female with green coat and straight tail is crossed to a male with black coat and curly tail. All the "Boutu" offsprings fall within one phenotypic class: green coat and curly tail. Blank 1- For each trait indicates which allele is recessive and which one is dominant. PART B) The reciprocal cross from A) is performed. Blank 2- Indicate the phenotype of each parents in the reciprocal cross. The F1 progeny of the reciprocal cross falls into the following phenotypic classes: all the females have green coat and curly tail; all the males have black coat and curly tail. Blank 3-How do you interpret the different outcome for the reciprocal cross? i.e. which genetic pattern explains the progeny of the reciprocal cross. Blank 4-Using A and a for the two alleles of coat color and B and b for the two alleles of tail shape, write the genotypes of the parents in the reciprocal cross. Be careful, use correct notation. Remember that they are true breeding.
