Step 1
Since Eldarion has two copies of each dominant allele, he can only pass on the dominant alleles to his offspring. However, if his human wife has at least one copy of each dominant allele, there is a chance that their child will inherit all three dominant alleles Show more…

The father of Mr. Spock, first officer of the starship Enterprise, came from planet Vulcan: Spock's mother came from Earth. A vulcan has pointed ears (determined by the allele P), green blood (determined by G), and right-sided heart (determined by R). All these alleles are dominant to normal Earth alleles. The three loci are autosomal, and they are linked as shown: P---20mu---G---30mu---R. If Mr. Spock marries an Earth woman and there is no (genetic) interference, what proportion of their children will have human phenotypes for all three characters? A. 7% B. 12% C. 28% D. None

Vulcans have pointed ears (determined by allele $P$ ), absent adrenals (determined by $A$ ), and a right-sided heart (determined by $R$ ). All these alleles are dominant to normal Earth alleles: rounded ears (p), present adrenals (a), and a left-sided heart (r). The three loci are autosomal and linked as shown in this linkage map: Mr. Spock, first officer of the starship Enterprise, has a Vulcan father and an Earthling mother. If Mr. Spock marries an Earth woman and there is no (genetic) interference, what proportion of their children will have a. Vulcan phenotypes for all three characters? b. Earth phenotypes for all three characters? c. Vulcan ears and heart but Earth adrenals? d. Vulcan ears but Earth heart and adrenals?
Genetic Problems I: The center for the study of hobbits located in Hobbiton obtained the following results using knobby knee and normal knee hobbits of unknown genotypes. Here is the result of the study group phenotype: Cross | Parents (Female/Male) | Offspring (Knobby/Normal) I | Knobby | Normal | 82 | 78 II | Knobby | Knobby | 118 | 39 III | Normal | Normal | 0 | 50 IV | Knobby | Normal | 74 | 0 V | Knobby | Knobby | 90 | 0 Consider both knobby parents in cross V are homozygous. Use N for dominant and n for recessive allele. Based on data provided; 1) What are the genotypes of parents in each cross? You must draw the punnett square for each cross and show your work. (4 points) 2) What is the type of Inheritance? (1 points) 3) If the knobby knee female in cross I were mated with the knobby male in cross V, what is the genotypes ratio for offspring? Draw punnett square. (2points)
