Please illustrate the segregation of genes responisible for the varied eye color and aldolase activity patterns for the bellow F2 ratio shown below.

RE = Red eye SE = Sepia eye A+ = Aldox(+) A- = Aldox(-)

Result:

9:1:!:3
(RE/A+ : SE/A+ : RE/A- : SE/A-)

Why don't you do it yourself? It's textbook stuff

This is a dihibrid cross. I can't draw a punnet square here. But the result 9:1:1:3 is not correct. Draw the punnet square and remember to count heterozygous as dominant characters and you will find out the real correct result.
