Horses have three basic coat colors: red (or chestnut), bay, and black. All the colors are controlled by the interaction of two genes, called Extension (E) and Agouti (A). The following combinations produce the bay color: EE/Aa, EeAa, EE/AA, and Ee/AA. Only two produce black color: EE/aa and Ea/aa. Other combinations of the alleles of these genes plus mutations of other genes result in many possible coat colors and patterns in horses. What type of inheritance does coat color in horses represent? (1 point) Responses

Horses have three basic coat colors: red (or chestnut), bay, and black. All the colors are controlled by the interaction of two genes, called Extension (E) and Agouti (A).

Other combinations of the alleles of these genes plus mutations of other genes result in many possible coat colors and patterns in horses. What type of inheritance does coat color in horses represent? (1 point) Responses

dominant inheritance
polygenic inheritance
mendelian inheritance
recessive inheritance

This is the original strand of DNA: ATG AAG TTT GGC TAA Which option would represent a frameshift mutation due to deletion during replication? (1 point) Responses ATG AAG TTG GCT AA ATG AAG TTG GCT AA
ATG TTT GGC TAA ATG TTT GGC TAA
ATG UAA GTT TGG CTA A ATG UAA GTT TGG CTA A
ATG AAG TTT GGC GCA TAA

Answer 1

The type of inheritance that coat color in horses represents is polygenic inheritance.

The option that represents a frameshift mutation due to deletion during replication is: ATG TTT GGC TAA.
