Question

Recall that GG and Gg individuals are gray bodied, while gg individuals are black bodied and that LL and Li individuals have long wings, while ll individuals have vesgial wings. What are the phenotypes of the resulng oHspring and what are the percentages of these phenotypes (2 pts)?

Answer 1

Answer:

- Gray-bodied with long wings: 56.25%.

- Gray bodied with vestigial wings: 18.75%.

- Black-bodied with long wings: 18.75%.

- Black-bodied with vestigial wings: 6.25%.

Explanation:

Hello,

In this case, we can write the involved two-factor Punnet square as:

                    GL       Gl        gL        gl

GL            GGLL    GGLl    GgLL    GgLl

Gl             GGLl     GGll      GgLl     Ggll

gL            GgLL     GgLl     ggLL    ggLl

gl             GgLl      Ggll       ggLl     ggll

Thus, we can find the following phenotypes:

- Gray-bodied with long wings: 9.

- Gray bodied with vestigial wings: 3.

- Black-bodied with long wings: 3.

- Black-bodied with vestigial wings: 1.

In such a way, considering each square having a 6.25% percent, the resulting offspring has the following percentages:

- Gray-bodied with long wings: 56.25%.

- Gray bodied with vestigial wings: 18.75%.

- Black-bodied with long wings: 18.75%.

- Black-bodied with vestigial wings: 6.25%.

Best regards.
