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.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
