Answer 1

Answer:

1)    50% of the progeny will be yellow and rounded, G-W-

      50% of the progeny will be yellow and wrinkled, G- ww

      0% of the progeny will be green and rounded, ggW-

      0% of the progeny will be green and wrinkled, ggww

2) The well 5 will contain the 8-cutter

Explanation:

1) Available data:

• yellow pea pod color (G) is dominant to green pea pod color (g)

• round seeds (W) are dominant to wrinkled seeds (w)

Cross: GGWw x ggww

Parental)  GGWw     x     ggww

Gametes) GW GW Gw  Gw  

                 gw   gw   gw   gw

Punnet Square)    GW        GW       Gw        Gw

                 gw    GgWw    GgWw   Ggww   Ggww

                 gw    GgWw    GgWw   Ggww   Ggww

                 gw    GgWw    GgWw   Ggww   Ggww

                 gw    GgWw    GgWw   Ggww   Ggww

F1) 8/16 = 4/8 = 2/4 = 1/2 GgWw

     8/16 = 4/8 = 2/4 = 1/2 Ggww

    50% of the progeny will be yellow and rounded, G-W-

     50% of the progeny will be yellow and wrinkled, G- ww

      0% of the progeny will be green and rounded, ggW-

      0% of the progeny will be green and wrinkled, ggww

2) The well 5 will contain the 8-cutter
