Which statement best contrasts polygenic inheritance with multiple allele inheritance?

a. polygenic inheritance results in offspring with only recessive alleles, while multiple allele inheritance results in offspring with both dominant and recessive alleles.
b. multiple allele inheritance results in offspring with only recessive alleles, while polygenic inheritance results in offspring with both dominant and recessive alleles.
c. polygenic inheritance is controlled by many genes, while multiple allele inheritance is controlled by three or more different forms of a single gene.
d. multiple allele inheritance is controlled by many genes, while polygenic inheritance is controlled by three or more different forms of a single gene.

Polygenetic inheritance happens when a certain characteristics are controlled by either two or more genes while multiple allele inheritance occurs when one inherits only half of the genes. In this problem, the best statement that contrasts polygenetic inheritance to multiple allele inheritance is letter B.

A.Polygenic inheritance results in offspring with only recessive alleles, while multiple allele inheritance results in offspring with both dominant and recessive alleles.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
