1.) a grasshopper with red stripes mates with a grasshopper with yellow stripes. What ratio would you expect to see in the phenotypes of their offspring?
A. all with yellow and red stripes
B. 1 with red stripes: 2 with red and yellow stripes: 1 with yellow stripes
C. all with red stripes
D. 2 with red stripes: 2 with yellow stripes <-- ?
***
2.) Which of the following best describes the relationship between a gene and an allele?
A gene is always dominant to an allele.
A gene is always recessive to an allele.
A gene is a variant of an allele.
An allele is a variant of a gene. <-- ?
***
3. Which of the following is the best physical description of a gene?
A gene is a specific segment of DNA on a chromosome. <--?
A gene consists of all of the DNA on a chromosome.
A chromosome is a segment of a gene.
Genes carry many chromosomes.
***
4. Suppose you cross a true-breeding blue flower with a true-breeding yellow flower. In the next generation, all of the flowers are blue. What does this outcome tell you about the allele for blue flowers?
The blue allele shows incomplete dominance.
The blue allele is recessive to the yellow allele.
The blue allele is sex-linked.
The blue allele is dominant to the yellow allele. <--?

1. This one is pretty difficult because you do not explain which grass hopper has the dominant gene (i.e. stripes). If the red striped grasshopper is the dominant, than it will be C.
2. A gene is always dominant to an allelle.
3. Your answer.
4. The blue allelle shows incomplete dominance.
