Question

Pea flowers may be purple (P) or white (p). Pea seeds may be round (R) or wrinkled (r). What proportion of the offspring form a cross between purple-flowered round-seeded individuals (heterozygous for both traits) will have both white flowers and round seeds?

Answer 1

Answer:

3/16

Explanation:

The following is the punnet square which  represents the probabilities of offsprings being produced for this cross:

            PR          Pr          pR          pr

PR         PPRR    PPRr      PpRR      PpRr

Pr          PPRr      PPrr      PpRr        Pprr

pR         PpRR     PpRr      ppRR      ppRr

pr          PpRr      Pprr       ppRr       pprr

This cross shows that the probability of the offsprings to have white flowers and rounded seeds would be 3/16.
