Question

Mendel found that yellow pea pod color (G) was dominant to green pea pod color (g), and that round seeds (W) were dominant to wrinkled seeds (w). What percentage of each of the phenotypes below are expected from the following cross? GGww x GgWw
Yellow and round

A.
0%

B.
25%

C.
33%

D.
50%

E.
66%

F.
75%

G.
100%



-
Yellow and wrinkled


-
Green and round


-
Green and wrinkled

Answer 1

Answer:

50% Yellow and Round

50% Yellow and Wrinkled

0% Green and Round

0% Green and Wrinkled

Explanation:

Checking both characteristics on each own we have that

For pea pod colour,

$\begin{center}\begin{tabular}{ | c | c | c| } & G & g \\ G & GG & Gg \\ G & GG & Gg \end{tabular}\end{center}$

Since Yellow (G) is dominant over Green (g) we have that:

GG - Yellow

Gg - Yellow

100% would be Yellow

For seeds format,

$\begin{center}\begin{tabular}{ | c | c | c| } & w & w \\ W & Ww & Ww \\ w & ww & ww \end{tabular}\end{center}$

Since Round (W) is dominant over Wrinkled (w) we have that:

Ww - Round

ww - Wrinkled

50% would be Round and 50% would be Wrinkled
