1) Write the possible genotypes of the two parents in each of these pairings. List all blood groups to which children of each of the following pairs of parents could belong.

Find possible parent genotypes and possible child blood groups given the parents below

AB X O:

2) A. How many different diploid genotypes are possible for a gene that exists in seven allelic forms? Please explain.
   B. How many different haploid genotypes are possible for a gene that exists in only three allelic forms? Please explain.

Solution

Answer:

Possible child blood group. Possible parent genotype

O, A, OO,AO

A,AB,B AO,AB,BO

B,O. BO, OO, BO,

AB,AO,BO,OO. AB,AO,BO,OO,

2. 49 diploid genotypes are possible. (N)2 is the firmula for deploidset. (N)3 for triploid...like this way. Follow basic principles of Hardy-Weinberg principles.

3. Six allelic forms are in rule. Sometimes exceptions are there.
