What percentage allow be lanky? c. What are the elementtic constitutions and phenotypes? moderate your work. suffices: a. 0% b. 100% c. 1 homozygous pre ascendant: 1 heterozygous; 100% tall 2. If Mendel wanted to determine the genotype of a yellow wheel pea, what would be the best plant to cross it? a. GgWw b. GGWW c. ggWW d. GGww e. ggww Check your work. Answer is e. If the genotype of an individual is to be tested, the best cross to actualize is the testcross, to a homozygous recessive. alone of the other crosses leave behind furnish potential recessive alleles in the yellow round plant to remain masked. 3. What phenotypic balance of offspring should be expect from the cross AaBb x AAbb? Check your work. Answer is d. Consider individually gene separately. Aa x AA will only produce offspring with the A phenotype. Bb x bb is the testcross of a monhybrid, so will produce a 1:1 ratio. One grad will have genotype AABb and AaBb and the other class will be composed of AAbb and Aabb individuals. 4. In grab occurs, a gene that produces a unclouded belt (B) nearly the animals consistency is dominant over its allele for a uniformly colored body (b).

Another gene produces a partnership of the two hoofs on each foot, a condition know as syndactylism is mated with a female betrayer that is normal-footed and homozygous for the belt ou t character. a. What are the genotypes of t! he male and female hog? b. What would be the phenotype ration out? Check your work: Answers: a. male blistery is bbTT b. female hog is BBtt c. phenotype is 16:0 all white belt syndactyly 5. Lauren, who has credit line type AB, marries Sal who has type B broth but whose mother has type O. a. List the genotypes of Lauren, Sal and Sals mother. b.
