In a monohybrid cross, if the gene for tall (t) plants was incompletely dominant over the gene for short (t) plants, what would be the predicted result of crossing an intermediate (tt) plant with a tall (tt) plant? (hint: you may want to complete a punnett square). a] 50 percent tall, 25 percent intermediate, 25 percent short. b] 25 percent tall, 50 percent intermediate, 25 percent short. c] 50 percent tall, 50 percent intermediate. d] 100 percent intermediate

The result of the cross of an intermediate plant (Tt) with a tall plant (TT), when the tall gene (T) is incompletely dominant over the short gene (t) will be as shown in the punnet square below. The gametes formed will be T , T , T, and t (Where T is the allele for tall while t is the allele for short).

The punnet square shows that the 50 % of the progeny of this cross will be tall (TT), and the other 50% will be intermediate (Tt). Hence, the correct answer is 'Option C - 50 percent tall, 50 percent intermediate'.

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
