8. In horses, black coat color is determined by a dominant allele B and brown coat color by its recessive allele b. The trotting gait is due to the dominant allele T and the pacing gait is due to its recessive allele t. If a homozygous black/pacer is mated to a homozygous brown/trotter, what will be the genotypes and phenotypes of the offspring

In horses, black coat color is determined by a dominant allele B and brown coat color by its recessive allele b. The trotting gait is due to the dominant allele T and the pacing gait is due to its recessive allele t. If a homozygous black/pacer is mated to a homozygous brown/trotter, what will be the genotypes and phenotypes of the offspring .

BBtt X bbTT= BbTt, BbTt, BbTt, BbTt

Explanation:

The genotype of the offspring Heterozygous Black trotting gait while the phenotype is all Black trotting gait.

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.
