Note: I have replaced copper with light brown for all of these! They have the same meaning, but I just thought that saying "light brown" rather than copper would be a bit more clear.

Mother (slightly changed appearance): Leafstep, a gray furred she-cat with forest green eyes

Father (slightly changed appearance): Copperstorm, a light brown (cinnamon) mackerel tabby tom with gray eyes.

(I'm not actually sure if gray eyes exist, someone please let me know if they do!)

Original appearances:

Cloverlight: A light gray mackerel tabby she-cat with a lighter underbelly and paws, and green eyes.

Sapdrip: Light brown (cinnamon) tom with amber eyes (I really like this name!)

Doefoot: Light brown spotted tabby tom with amber eyes.

Genetically accurate appearances:

Cloverlight: Light gray mackerel tabby she-cat with green eyes.

Sapdrip: No changes

Doefoot: No changes

Explanation:

Cloverlight is a light gray mackerel tabby she-cat with green eyes, because cats cannot have an underbelly and paws lighter than their pelt color, unless their underbelly and paws are white.

Fur color is sex-linked, which means that the genes for fur color are found in a cat's X chromosomes. Female cats usually have two X chromosomes, and males normally have one X and one Y chromosome. Since Cloverlight has two X chromosomes, she receives one gene from Copperstorm's X chromosome, and one gene from either one of Leafstep's X chromosomes. 

Next, the dilution gene is responsible for making Cloverlight into a gray cat! Dilution is not sex-linked, so regardless of gender, each cat gets two genes for this trait. Non-dilution (represented with a capital D) is dominant to dilution (represented with a lowercase d), so in order for Cloverlight to be gray, she must receive one dilution gene from each parent. Leafstep is gray, and since gray is the dilute form of black, she has the genotype dd. Copperstorm is cinnamon, which is not a diluted color, so he could either have the genotype DD or Dd (where one is non-diluted, and the other one is a non-diluted cat carrying the gene for dilution). But since we need Cloverlight to be gray, Copperstorm would have the genotype Dd, so that Cloverlight could receive one dilution gene from each parent.

And lastly, the tabby markings. The proper word for a tabby cat is an agouti cat, and the agouti gene (represented with a capital A) is dominant to the non-agouti gene (represented with a lowercase a). This is also a non sex-linked trait! Leafstep is solid gray so she would carry no agouti gene, but since Copperstorm is a cinnamon tabby, he carries at least one copy of the agouti gene. Receiving the agouti gene from her father, and the non-agouti gene from her mother, the agouti gene would mask the effects of the non-agouti gene, making her a gray tabby! A mackerel tabby, to be exact, since she would receive the gene for mackerel tabbies from Copperstorm.

Sapdrip remains a cinnamon tom. Since he has one X and one Y chromosome each, he receives one gene from Leafstep's X chromosome, and a Y chromosome from Copperstorm. Because of this, toms can only get their fur color from their mother, and not their father.

Since Sapdrip is not a dilute cat, he would recieve one dilution gene from his mother, and one non-dilution gene from Copperstorm, making him a non-diluted cat, carrying the gene for dilution.

And since Sapdrip is solid colored, he would need two copies of the non-agouti gene. Leafstep has the genotype aa, so if Copperstorm had the genotype Aa, Sapdrip would recieve one agouti gene from Copperstorm, and one non-agouti gene from Leafstep, making him a tabby cat.

FINALLY, on to Doefoot, who remains a cinnamon spotted tabby tom. Doefoot's fur color/dilution is the same as Sapdrip's so I'll skip those parts.

You described Sapdrip as a cat with darker spots, which is a spotted tabby. This means that Sapdrip must have at least one copy of the agouti gene. Receiving one agouti gene from Copperstorm and one non-agouti gene from Leafstep, Sapdrip would have the genotype Aa.

The spotted tabby gene has very little knowledge on it, but experts theorize that the spotted tabby gene is a dominant gene that breaks up tabby lines, making them into smaller spots. Since Copperstorm is a mackerel tabby, he does not have the spotted tabby gene. However, Sapdrip could recieve the spotting gene from his mother. Though Leafstep isn't a tabby cat, she could still carry the spotted tabby gene, it just doesn't show on her pelt because she doesn't have the agouti gene that allows tabby markings to show up in the first place. So he would inherit one spotted tabby gene from his mother, and one non-spotted tabby gene from his father, making him a spotted tabby.

Thanks for requesting! Sorry if this was kind of long!
