To determine:
Which baby belongs to which couple by using the given information?
Concept introduction:
The ABO blood group is determined by three alleles of gene I:
If gene I encodes for both molecule A and B, it give rise to blood group type AB (genotype

Explanation of Solution
Tabular representation:
Table 1: Cross between father with genotype
Table 2: Cross between father with genotype
Table 3: Cross between father and mother with genotype
Table 4: Cross between father and mother with genotype
Table 5: Cross between one parent with genotype
Table 6: Cross between father with genotype ii and mother with genotype
Table 7: Cross between father with genotype ii and mother with genotype
Couple 1: Father with B blood type (genotype
If the father has genotype
If the father has genotype
Thus, couple 1 could produce children with blood type A, B or AB.
Couple 2: Father have blood type A and mother have blood type A. Both could have genotypes
If both father and mother have genotype
If both father and mother have genotype
If one parent have genotype
Thus, couple 2 could produce children with blood type A, or O.
Couple 3: Father with blood type O (genotype ii) and mother with blood type B (genotype
If father has genotype ii and mother has genotype
If father has genotype ii and mother has genotype
Thus, couple 3 could produce children with blood type B, or O.
According to the given information:
Baby X has blood type B.
Baby Y has blood type AB.
Baby Z has blood type O.
As only couple 1 could produce children with blood type AB, so baby Y belongs to couple 1.
As only couple 3 could produce children with blood type B, so baby X belongs to couple 3.
As couple 2 could produce children with blood type O, so baby Z belongs to couple 2.
Baby X belongs to Jordan and Taylor, baby Y belongs to Logan and Leslie and baby Z belongs to Sam and Casey.

- When beta-lactamase was isolated from Staphylcoccus aureus and treated with a phosphorylating agent, only the active site, serine was phosphorylated. Additionally, the serine was found to constitute 0.35% (by weight) of this beta-lactamase enzyme. Using this, calculate the molecular weight of this enzyme and estimate the number of amino acids present in the polypeptide.arrow_forwardBased on your results from the Mannitol Salt Agar (MSA) media, which of your bacteria were mannitol fermenters and which were not mannitol fermenters?arrow_forwardhelp tutor pleasearrow_forward
- Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
