Explanation / Answer

PART 1 :

1a) YY                X              Yy

1b)

2) a) Resulting phenotype is YELLOW.

b) No there are no blue kernels.I can tell it as there is no "yy" genotype in the above cross.It is a recessive trait and can only be expressed when both the recessive alleles are present.

c) It can be known by lookingb at the phenotype and genotype.

3) Cross between    Yy                 X                   Yy

4) a)Genotype are : YY,Yy,yy and ratio is 1:2:1.

b) Their phenotype is both yellow and blue.Ratio is : 3:1

c) There are more blue kernel than F1 as there were no blue kernels were formed in F1.

5) a) YYSs : YS ; YS ; Ys ; Ys

b) YYSs : YS ; YS ; Ys ; Ys

c) cross between         YYSs            X              YYSs

d) phenotypes : yellow wrinkle (YYSS,YYSs) and yellow smooth (YYss)..Ratio is : 3:1

e) Ratio : 3: 1

Y y Y YY (yellow) Yy (yellow) Y YY (yellow) Yy (yellow)
