- Pedigree 3: NOTE: the asterisk (*) indicates that the individual does not have any disease-related alleles. A. What is the most likely mode of inheritance of this disease? Choose from: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive. B State the genotypes of individuals #1 - #4. C What is the probability of individual A being affected (show the disease)? What is the probability of individual B being affected?

- QUESTION 1 Crosses between a pure-breeding strain of white beet plants and a pure-breeding strain of yellow beet plants produced all white beet plants. The F1 plants were crossed to each other (self-cross) and the following F2 plants were observed: 95 white beet plants, 25 red beet plants and 7 yellow beet plants. How many genes determine beet color? Give the genotype of the parental white beet plant and the yellow beet plant. (Use A for a single gene inheritance, A and B for two gene inheritance and A, B, C for three gene inheritance. Write the genotype using proper notation.) Genotype of P1 white beet plant: Genotype of P1 yellow beet plant: What phenotypic ratio is observed in the F2 progeny? (List the ratio as a complete fraction next to the phenotype). Example: ½ purple Write the genotypes of the following F2 beet plants. (Write the genotype using proper notation.) Genotype of the F2 white beet: Genotype of the F2 red beet: Genotype of the F2 yellow beet:arrow_forward15,16arrow_forwardHow do we get the expected?arrow_forward
