Start with “Co-Dominance” and read and do
everything on the site. However while you need to fill in the tables on the site
to figure things out, you do not have to answer the questions in the boxes on
the site. Below you will find boxes with some of their questions, and some of my
own. You will be graded on these answers.
Answer the questions as best you can. The boxes will expand as you type if you need more space.
(Don't worry if it is a one word answer. The box size is standard.)
Question 1: On page 3 of 16, what is the color pattern of the fly
Question 2: Define Co-dominance.
Question 3: How is co-dominance different from incomplete dominance?
Question 4-5: Fill in the Punnett Square for the cross below: For each of the
empty boxes enter the Genotype and the Phenotype and if it is heterozygous or
homozygous. I have done half the square for you.
Remember, the boxes will expand as you type if you need more space.
Question 6: Based on the Punnett square what would you expect for two black
bodied flies who produced 2000 offspring?
Question 7-8: Fill in the Punnett Square for the cross below. For each of
the empty boxes enter the Genotype, and the phenotype and if it is heterozygous
or homozygous. I have done half the square for you.
