White coat (w) is dominant over tan (w) coat in foxes. when a white-coated male is mated with a tan-coated female, 100% of their offspring are white-coated. what is the genotype of the female fox?

That's wrong. The correct answer is D.) ww

The genotype of the female fox is-

ww.

As per the given information in the question, white coat (W) is dominant over tan (w) coat in foxes.

Dominant trait (depicted by capital letter allele, such as W for white coat) masks the expression of recessive trait (depicted by small letter allele, such as w for tan coat).

This means that white coat is a dominant trait over the tan coat, which is a recessive trait.

The only possible genotype for tan coat is 'ww' (homozygous recessive), whereas white coat can be exhibited by two genotypes, WW (homozygous dominant) and Ww (heterozygous dominant).

As the female is tan coated fox, thus her genotype would be ww (homozygous recessive).

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.
