CHAPTER 10 & 11 PRACTICE PROBLEMS PUT A FULL HEADING ON YOUR LOOSE LEAF. COMPLETE THE FOLLOWING PROBLEMS

DRAW A PUNNETT SQUARE and give the phenotypic & genotypic percents FOR EACH 1. A homozygous dominant purple plant is crossed with a heterozygous purple plant. (P) Recessive is white. 2. A Black heterozygous rabbit is crossed with another heterozygous black rabbit. (B) Recessive is white. 3. A homozygous recessive yellow seed plant(Y) is crossed with a heterozygous green seed plant.

DRAW A PUNNETT SQUARE and give the phenotypic & genotypic ratios FOR EACH 4. A heterozygous purple tall plant is crossed with another one with the same genotype (TtPp). 5. A family has 3 boys, what is the probability that they will have another boy? A girl? Give your answer as a fraction. 6. A red snapdragon flower is crossed with a white snapdragon flower.

DRAW A PUNNETT SQUARE and give the phenotypic & genotypic ratios FOR EACH 7. If a Dad has Type AB blood( IAIB) and the Mom has Type A (IAi) blood, what type blood could their children have? 8. If a Dad has Type B blood (IBi) and the Mom has Type O blood (ii), what type blood could their children have? 9. What are the possible genotypes for a chocolate Lab?

DRAW A PUNNETT SQUARE and give the phenotypic & genotypic ratios FOR EACH 10. A female carrier for hemophilia marries a man who is not a hemophiliac. Is it possible for them to have a child with the disease? Why or why not? Does it matter if the child is a male or a female? Why or why not?
