BIO HELP In Labrador Retrievers, coat color is controlled by an epistatic gene. Examine the image below to determine which gene is epistatic and controls the phenotypic expression of the other.

1) Gene “E” (EE, Ee, or ee) is the epistatic gene.

2) Gene “B” is the epistatic gene.

3) The genotype “bb” is epistatic.

4) It cannot be determined from this image.

the answer would be..

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

you know they are heterozygous for a trait because they have it as jj or jj.
