Question

What are the genotypes/phenotypes of the following types of retreads from the diploids? 5. Consider the follow ing cross: MATa lys2 MATa ura3 What resulting diploids when considering only the ura3 and hys2 loci. a. Parental Ditype (PD) are the genotypes and phenotypes of the following types of tetrads that could occur from the PD genotype (ura3-lys2) PD phenotype b. Non-parental Ditype (NPD) NPD genotype ura3-lys2) NPD phenotype c. Tetratype (TT) TT genotype (ura3-lys2) TT phenotype d. What are the genotypes and phenotypes of an NPD when considering the ura3 and MAT loci? NPD genotype MAT-ura3) NPD phenotype Worksheet: Yeast Tetrad Analysis

      ura3 lys2-       ura3
      ura3 lys2-       ura3
      ura3- lys2       lys2
      ura3- lys2       lys2

C. TT genotype      Phenotype
      ura3 lys2        ura3/lys2
