Genetics Quiz #2 PUNNETT SQUARES

Question #1: A white flowered plant is crossed with a plant that is heterozygous for the trait. What percentage of the offspring will have purple flowers? A. 0% B. 25% C. 50% d.75% E. 100%

Question #2: "Could a man with type B blood and a woman with type AB produce a child with type O blood?“-must show punnett square for grade. A. yes B. no C. I’m not sure

Question #3: The actual genes that an organism has are its __________. A. gene type B. phenotype C. genotype D. physical appearance E. karyotype

E. non of them are correct Question #4: In squirrels, the gene for gray fur (G) is dominant over the gene for black fur (g). If 50% of a large litter of squirrels are gray, the parental cross that produced this litter was most likely: (a.) GG x Gg (b.) Gg x gg (c.) GG x GG (d.) gg x gg E. non of them are correct

Question #5: In a certain species of mouse, gray fur (G) is dominant over cream-colored fur (g). If a homozygous gray mouse is crossed with a cream-colored mouse, the genotype of the F1 generation will most likely be (a.) 100% Gg (b.) 25% GG, 50% Gg, and 25% gg (c.) 50% GG and 50% gg (d.) 75% Gg and 25% gg (e) none of them
