Punnett square worksheet. Complete the following monohybrid crosses: draw a Punnett square, list the ratio and describe the offspring. Be sure to remember that the capital letter is dominant. Example) A green pea plant (GG) is being crossed with a green pea plant (Gg).
a. Construct a Punnett square for this cross. b. What is the expected phenotypic ratio for the offspring? 2. In humans there is a disease called Phenylketonuria (PKU)which is caused by a recessive allele. People with this allele have a defective enzyme and cannot break down the amino acid phenylalanine.
