The gene d controls wing shape in flies and has two alleles: d is wild-type and dominant, and d is recessive and causes flies to have downward pointed wings. the gene e controls eye development and also has two alleles: e is wild-type and dominant, and e is recessive and causes the flies to have small eyes. the two genes are located on the same chromosome. a pure-breeding fly with normal wings and small eyes was crossed with a pure-breeding fly with downward wings and normal eyes. all of the f1 progeny had a wild-type phenotype. the recombination frequency between the two genes is 14%. if an f1 individual was test crossed, what percentage of the progeny would you expect to have the wt phenotype? 43%7%28%14%86%

7 % progeny will show wild type phenotype

Explanation:

Parent 1: Normal wings and small eyes : DDee

Parent 2 : Downward wings and normal eyes : ddEE

DDee X ddEE = DdEe ( All have normal wings and normal eyes )

When a F1 individual is test crossed:

DdEe X ddee =

De/de = Parental

dE/de = Parental

DE/de = Recombinant

de/de =  Recombinant

Recombination frequency between the two genes is 14% hence DE/de and de/de will each have 7% frequency. Since DE/de ( DdEe ) will give wild type phenotype, it means that 7% progeny will have wild type phenotype.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
