Basha: A blood type, blue eye color, normal skin condition, carrier of cystic fibrosis gene, and carrier of hemophilia gene Popoy: B blood type, has brown eye color, normal skin condition, carrier of cystic fibrosis gene and negative to hemophilia. Clues for the table: • Blood Type: The probability that they’ll have an offspring with blood type the same as Popoy is 25% only • Eye Color: The probability that they’ll have an offspring with brown eye color is 75%. • Skin condition: The probability that their offspring will be an albino is 25%. What is the probability that the offspring will have/ be: A. a girl with all the same phenotype as her mother. B. 2 girls with neither the blood type of the parents.

A normal woman, whose father was a hemophiliac, marries a normal man. Determine the genotype of the woman and the man. Determine the possible genotypes of their children. What percent of male and female children would be hemophiliacs? What percent normal? Would any be carriers?
The same lab tested Prince Harry and Megan Markle. They confirmed that Harry does have hemophilia, Megan does not have hemophilia and is not a carrier for it. Which of their offspring are at risk for having hemophilia? a-Male offspring b-Female offspring c-All offspring d-No offspring
Based on the genotypes presented here, what would be the phenotypic ratio of the F1 generation? A. 3 hemophilia: 1 non- hemophilia b. 4 hemophilia: 0 non- hemophilia c. 1 hemophilia: 3 non hemophilia d. 2 hemophilia: 2 non- hemophilia
Given: Father - heterozygous for the H locus of the H antigen, heterozygous for the B locus of the ABO blood group system, heterozygous for the D locus of the Rh blood group system, and deuteranope Mother - heterozygous for the H locus of the H antigen, heterozygous for the A locus of the ABO blood group system, heterozygous for the D locus of the Rh blood group system, and carrier for the trait deuteranopia Task: Using the line fork method, determine the probabilities in ratio form of all possible phenotype combinations of the traits in the biological offspring of the couple.

A normal woman marries a man with sickle-cell trait. What is the probability of their having a (a) child with sickle-cell trait, (b) normal child, (c) child with sickle cell anemia?
Complete a new Punnett square below, for a woman who is a carrier for sickle cell, who is married to a man who has sickle cell. What are the possible genotypes that you can identify, what is the ratio of phenotypes that are possible, and what is the chance that any of the offspring are affected by sickle cell anemia?
Define the allele associated with this form of anemia, and define the NORMAL allele of this same gene. Be sure to indicate which is which.
The following is a summary of the possible sickle-cell genotypes and phenotypes: AA - cojmpletely normal AS - sickle-cell trait (this person has a combination of normal hemoglobin and the abnormal, sickled form of hemoglobin) SS - sickle-cell anemia (all abnormal hemoglobin) If both parents and heterozygous for sickle-cell disease, what are the possible genotypes and phenotypes for their children?
A woman with blood type O has a child with blood type O. Her husband, whose blood type is AB is concerned that the child may not be his. Based on what you learned from the inheritance of the ABO blood group system, what conclusions would you make? (Assume that both parents and the child normally produce the H-substance). The husband is right to be concerned because the only possible blood group types expected from both parents are type A or B or O. The husband should not be concerned. Since the child has the exact same blood type of the mother, the child simply inherited the blood type from her mother. The husband is right to be concerned because the only possible blood group types expected from both parents are type A, B, or AB. The husband should not be concerned because he may be a carrier of the O allele. The husband should not be concerned. Since the O allele is dominant, it makes sense that the child should show the O blood type.
