Assume that you have a garden and some pea plants have solid leaves and others have striped leaves. You conduct a series of crosses ((a) through (e)l and obtain the results given in the table Define gene symbols and give the possible genotypes of the parents of each cross.

Solution

If we consider solid S is dominant over striped s ,then SS ans Ss will be dominant and ss will be striped.Accordingly,

a) solid * striped :

parental Solid will be Ss and parental striped will be ss.The progeny will be both solid and striped.

b) solid * solid

Both parental genotype will be SS and SS.The progeny will be all solid.

c) striped * striped

Both parental genotype will be ss.The progeny will be all striped.

d) solid * solid

Both parental genotype will be solid Ss and in progeny both solid and striped will be formed.

e) solid * striped

Parental genotypes will be solid SS and striped ss :The progeny will be Ss and all solid.
