Which statement best describes the potential confusion in early studies of inheritance patterns for skin color?
a. the polygenic trait apperared as incomplete dominance.
b. the polygenic trait apperared as codominance
c. incomplete dominance apperared to be a polygenic trait
d. codominance apperared to be a polygenic trait.

Answer;

The polygenic trait appeared as incomplete dominance.

Explanation;

-Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Examples of human polygenic inheritance are height, skin color, eye color and weight.

-Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles.

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)
