Short Answer/Fill-in/Essay
Rhodes-Little
1. What ratio did Mendel discover always existed between dominant to recessive traits in the 2nd generation?
2. From his experiments, Mendel made two conclusions.
How many sets of instructions for each characteristic does each parent plant donate to its offspring?
How many sets of instructions does each parent plant have for each characteristic?
Completion: Write the word(s) that best completes each statement below.
The two forms alleles come in are 3 and 4 .
If we reword Mendel’s conclusions, we can better understand his findings. When he stated that for each
characteristic each parent has “2 sets of instructions,” this now means 1 pair of “ 5 .” When he stated
that for each characteristic each parent donates “1 set of instructions,” this now means one “ 6 ” is
donated from each parent.
Symbols are used to represent dominant and recessive alleles. A 7 is used for a recessive allele and a
8 is used to represent a dominant allele.
Blood Types: Type A Type B Type AB Type O
9. ________ Which of the phenotypes above is a co-dominant blood type?
10. _______________ Which blood types above have more than one genotype combination to produce that blood type?
11. ______________________________________________________ Explain how it’s possible for a child to have
type O blood if neither parent’s phenotype is O?
Shepherd-Code
A newspaper column that answers reader’s questions received the following letter from a young girl.
Dear Mr. Know It All,
I am thirteen years old and my older sister is always teasing me and saying that I am adopted. When I ask my parents, they just laugh and say, “That’s silly,” but they never really say that I’m not. I don’t look anything like the rest of my family. Everyone in my family has brown eyes, but mine are blue. I have straight red hair, no one else in my family has red hair and most of my family has curly hair. Do you think they are just trying to hide the fact that I really was adopted? How can you explain all the differences?
The Family Misfit
Write a response explaining why she could have traits other then those expressed in the rest of her family. Be sure to include vocabulary that would help you explain and definitions for words that she may not know the meaning of. Remember you are writing as an adult working at the newspaper to a young girl.
