Question 3a and 8

1 Q3.Use the information in Table 4.1 and the genotypes you created for each chromosome pair for three traits: cleft chin, earwax form, and PTC tasting in question 2. a. Fill in the table below, making the genotype for each trait different for individuals 1, 2, and 3. Q8. A case of disputed paternity involves a woman, her children (1,2and 3) and two men(Y and Z).The analysis is limited to the ABO and Rh blood groups system. Use the space provided following the table for notes or punned squares. Assume that only Y or Z could be biological father; complete the following data table to assign each child his/her possible father. Remember that her ABO blood group system, Anad B are codominant and both are dominant over the recessive O allele>Rh has two alleles and d. Rh- is the recessive form associated with genotype dd. The ABO group and Rh type characterize a gathering of hereditarily acquired antigens tracked down in the external layer of every red platelet. The ABO bunch comprises of four prospects: A,B,AB,and O. The Rh type is either positive or negative. The Rh blood group is one of the most complex blood bunches known in humans. From its disclosure quite a while back where it was named (in mistake) after the Rhesus monkey, it has become second in significance just to the ABO blood bunch in the field of transfusion medication. Individual 1 Individual 2 Individual 3 Genotyp e Phenotype Genotyp e Phenotype Genotype e Phenotype Cleft chin cc Cleft chin Cc Normal chin, no cleft CC Normal chin, no cleft Earwax form AA Dry earwax GA Wet, sticky earwax GG Wet, sticky earwax PTC tasting t Inability to Tt Ability to TT Ability to taste PTC taste PTC taste PTC Tongue Rolling rr Inability to tongue roll Rr Ability to tongue roll RR Ability to tongue roll

2 Potential Dads for offspring 1: Y: Y is Rh+ and can pass on either the D or d allele. He can likewise pass on either the An or B allele. In this way, he can deliver offspring of any ABO and Rh blood classification. Z: Z is Rh− and can pass on the d allele. He can pass on either the An or B allele. Thusly, he can create offspring of any ABO blood classification, however just Rh− offsprings. Offspring 1 is Rh+ and has blood classification A. This implies that the offspring probably acquired the D allele from their dad and the An allele from their mom. Accordingly, the potential dads for Kid 1 are Y and Z. Potential Dads for Kid 2: Y: Y is Rh+ and can pass on either the D or d allele. He can likewise pass on either the An or B allele. Thusly, he can deliver offspring of any ABO and Rh blood classification. Z: Z is Rh− and can pass on the d allele. He can pass on either the An or B allele. Along these lines, he can deliver offspring of any ABO blood classification, yet just Rh-youngsters. Youngster 2 is Rh+ and has blood classification AB. This implies that the youngster probably acquired the D allele from their dad and both the An and B alleles from their mom. Since the mother is A, she can pass on the An or the O allele. In this way, the potential dads for Kid 2 are just Y. Potential Dads for offspring 3: Y: Y is Rh+ and can pass on either the D or d allele. He can likewise pass on either the An or B allele. In this way, he can deliver offspring of any ABO and Rh blood classification. Z: Z is Rh− and can pass on the d allele. He can pass on either the An or B allele. Consequently, he can create offspring of any ABO blood classification, however just Rh− offsprings. Youngster 3 is Rh− and has blood classification O. This implies that the offspring probably acquired the d allele from their dad and the O allele from their mom. Since the mother is A, she can pass on the An or the O allele. Accordingly, the main conceivable dad for offspring 3 is Z. All in all, the potential dads for offspring 1 are Y and Z, the conceivable dad for offspring 2 is just Y, and the main conceivable dad for Kid 3 is Z.
