Two genes determining a trait In primroses, the dominant allele of gene K is necessary to synthesize blue flower pigment. Blue pigment synthesis is inhibited by a dominant allele of gene D. In other words, plants with the genotype K- D- will not produce pigment (and their flowers will be white) because of the presence of the D allele. If you set up a testcross for (Kk Dd) plants what is the ratio of blue to white offspring in the progeny?

The ratio of blue to white offspring in the progeny is 4 blue : 12 white.

Explanation:

Available data:

Cross: testcross for (Kk Dd) plants

Parental)   KkDd     x     kkdd

Gametes) KD   kD   Kd   kd      

                kd   kd   kd   kd

Punnet square)        KD        Kd       kD       kd

                      kd     KkDd   Kkdd   kkDd   kkdd

                      kd     KkDd  Kkdd   kkDd   kkdd

                      kd     KkDd   Kkdd   kkDd   kkdd

                      kd     KkDd   Kkdd   kkDd   kkdd

F1) Progeny genotype: 4/16 KkDd, white-flowered plants

                                      4/16 Kkdd, blue-flowered plants

                                      4/16 kkDd, white-flowered plants

                                      4/16 kkdd, white-flowered plants

     The ratio of blue to white offspring in the progeny is 4 blue : 12 white.

     Blue-flowered plants: 4 Kkdd

     White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd

b because they naturally adapt to their environment plz mark brainliest

compost can be added to topsoil as a:

pesticide
