Solves the two problems shown below and then sketch, photograph, and submit your schemes (Punnett squares) of these crosses, showing all gametes, genotypes and resulting % of phenotypes.
a. A man with blood group A (heterozygous) marries a woman with blood group AB. What are possible phenotypes and their chance in their children?
b. Queen Victoria was a carrier of hemophilia; her husband was healthy. What were possible phenotypes and genotypes, and their chance in their children?

Explanation / Answer

a.Man :Blood group A :

Heterozygous A :genotype will be AO :

gametes will be A,O

Woman :Blood group

AB:genotype will be AB :

gametes will be :A,B man

Posiible phenotype: AB blood group:A blood group :B blood group = 1:2:1

Possible genotypes: AA ,AO,AB,BO

chance of child with AB phenotype = 1/4 = 0.25

chance of child with A phenotype = 2/4 = 0.5

chance of child with B phenotype = 1/4 = 0.25

b.

h represents:hemophilic trait

Queen victoria is carrier

her genotype: XhX

gametes :Xh,X

Husband is normal :

Genotype:XY

Gametes:X,Y male

Phenotype : normal son :normal daughter :hemophilic son = 1:2:1

Genotype :XhX ,XX,XhY,XY

Chance of normal daughter : 2/4 = 0.5

Chance of normal son :1/4 =0.25

Chance of hemophilic son :1/4 = 0.25

woman A O A AA A blood group AO A blood group B AB AB blood group BO B blood group
