As we can see the blood group of father is AB which will have genotype IAIB. The female has A blood group which can have genotype IAIA or IAi. These parents can form child with A and B blood group only. The O blood group is not possible as O blood group has genotype ii which is only possible when both parents has one i which is not present in AB. So the daughter is the child of this father but not son.
The answer is A.
Based on the following pedigree, with blood types provided (and ignoring the Bombay phenotype), what conclusions...
Q1. What is the difference between incomplete dominance and codominance? A. In incomplete dominance, the dominant phenotype is expressed in heterozygotes. In codominance, both phenotypes are expressed in heterozygotes. B. The phenotype reveals the genotype only in codominance. C. In both types of inheritance, the heterozygotes express the phenotypes dictated by both alleles. D. In codominance, both phenotypes are expressed in heterozygotes. In incomplete dominance, the heterozygote shows a phenotype that is intermediate between the two homozygotes. Q2. Based on...
1. For each of the following blood types, list the possible genotypes: Phenotype Possible Genotypes A B AB O 2. Dr. Paul is blood type O. His father was blood type A and his mother was blood type B. What were the genotypes of his parents? What are the possible blood types and phenotypic ratios expected for a cross involving these parental genotypes? 3. In the ABO blood system in human beings, alleles A and B are codominant and both are...

3) (2 pts) A man with type B blood and a woman with type O blood produce a male child with type AB blood. a) Provide a genetic explanation that includes the genotypes for each of the three individuals. b) If the male child above mated with a female with the same blood type (AB) and the same genotype, what is the probability of producing a child with O blood type? What about A blood type?

Human blood types A, B and O are associated with the carbohydrate antigens A, B and H respectively. A and B antigens are caused by an alteration of H antigen. Normally everyone can synthesize H antigen (a cell surface carbohydrate found on red blood cells and other cell types). Some people make A and/or B transferase(s) which converts the H antigen to an A and/or B antigen respectively. The H antigen is produced by a specific fucosyltransferase encoded by the...
There are three main alleles in the ABO blood group system -
IA, IB, and i. We've talked about the ABO
system in class, you can find a brief explanation below and
here.
The I gene encodes for a glycosyltransferase
that modifies at the H antigen.
The glycosyltransferase encoded by IA adds an 'A'
sugar group to antigen H, the glycosyltransferase encoded by
IB adds a 'B' sugar group and i encodes an inactive
glycosyltransferase that leaves the H antigen...
Question 4. Several different human antigens can be detected in blood tests. The following traits were tested for each individual shown below. Assume NO Bombay phenotype or carriers and all blood types assort independently. Rh type K type ABO type μ and 18 codominant, i recessive; MN type Xea) type Duffy type FvA and FyB codominant, Fy recessive to FyA & FyB The phenotvpes for the individuals are shown below Mother Daughter 1 Daughter 2 Alleged father1 Alleged father 2...

For these questions, you are using the A, B, and O to represent the alleles in this example. The ABO blood system works in a Mendelian fashion, but has 3 possible alleles at one locus (A, B, and O alleles). Each person can have only 2 of those alleles in their genotype. A and B are both dominant (and so can be co-dominant), and O is recessive to both A and B. So, for example, if you have B blood...
44) (3 pt) The following pedigree analyzes linkage between the ABO blood group and nail patella syndrome.
