Questions

1. A low chi-square value means probability that the observed deviation from the expected ratio is due to random chance alone. Therefore the Null hypothesis for chi-square test is accepted and the observed ratios and expected ratios must have a good fit.

 higher

 not useful to make any judgements

 lower

 zero

2. If the map distance between A and B is 17 map units (which is same as percentage recombination of 17 percent). then the different kinds of gametes will be produced in the following ratio:

 17:17:100:100 (first two represent parental chromosomes, the last two recombinant chromosomes)

 17:17:17:17 (first two represent parental chromosomes, the last two recombinant chromosomes)

 83:83:17:17 (first two represent parental chromosomes, the last two recombinant chromosomes)

 83:17:83:17 (first two represent parental chromosomes, the last two recombinant chromosomes)

 100:100:17:17 (first two represent parental chromosomes, the last two recombinant chromosomes)

3. In blood transfusions which of the following statements are relevant.

(many choice, select all that apply)

Recipient's plasma antibodies are most critical

Donor's plasma antibodies are most critical

Donor's BC antigens are most critical

Recipient's BC antigens are most critical

A person with the genotype / hh cannot make "A" antigen. (hint: H= wild allele for enzyme to make H antigen, h = loss of function allele).
