Question

Some traits of plants and animals depend on inheritance of a single gene. This is called Mendelian inheritance, after Gregor Mendel (1822-1894). Each of us has an ABo blood type, which deseribes whether two characteristics, called A and B, are present. Every one of us has two blood type alleles (gene forms), one inherited from our mother and one from our father. Eech of these alieles cen be A, B, or O. Which two we inherit determines our blood type. Here is a table that shows what our bloed type is for esch combination of two aleles Alleles inherited Blood type A and A A and B A and O s and B AB O and O We inverit each of a parem's two alieles with probebility O.5.We inherit indrgendently from our mother and father Emily and Michael both have alees O and o (a) What biood types can their children have (Select all that apply (b) What is the probablity that their next crild tas each of these blood types?

Answer 1

$Ans:~(a)~O.\\ (b)~P(A)=P(A~and~A)+P(A~and~O)=0.5^2+0.5^2=0.5\\ Since~we~inherit~independently~from~our~mother~and~father.\\ P(AB)=P(A~and~B)=0.^2=0.25\\ P(B)=P(B~and~B)+P(B~and~O)=0.5^2+0.5^2=0.25\\ P(O)=P(O~and~O)=0.5^2=0.25$
