Suppose that the eye color and wing shape genes assort independently (they are not linked, i. e., they are located on different chromosomes). In a mating between a female with the genotype w+m+/wm and a male of genotype wm/wm what percentage of the F1 progeny will have a non-parental genotype?

w+m+/wm x wm/wm = 1/2 w+m+/wm + 1/2 wm/wm

The percentage will be  50%

Explanation:

If the genes are not linked, the frecuency will have 1/2 (50% ) because it is the probability of segregation in the second meiotic division

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
