Which term describes the form of a gene that produces a specific trait such as eye color

1. In the late 1800s, Mendel predicted the existence of units of hereditary information or factors. What do we call these units of hereditary information today?  

chromosomes or genes im not sure  

2. Which term describes the form of a gene that produces a specific trait, such as eye color?  

allele  

3. Which term describes a type of trait that is usually expressed only when an organism has two identical alleles for the trait?  

homozygous  

8. Refer to the following information to answer Questions 8 and 9.  

A certain species of grasshopper can have red stripes, yellow stripes, or red and yellow stripes. An RR grasshopper has red stripes, an YY grasshopper has yellow stripes, and an RY grasshopper has red and yellow stripes.  

Which type of inheritance is this an example of?  

codominance  

9. 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?  

all with yellow and red stripes  

10. Which of the following best describes the relationship between a gene and an allele?  

An allele is a variant of a gene.  

11. Which of the following is the best physical description of a gene?  

A gene consists of all of the DNA on a chromosome.  

12. 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 is dominant to the yellow allele.
