A lizard with a striped tail and a normal head crossed with one having a normal tail and a spotted head produce all normal (no stripes or spots) F1 progeny. What progeny would be expected to be produced by mating either of the parental lizards with another that had a striped tail and spotted head, if the genes conferring stripes and spots were close together on the same chromosome?

9 normal : 3 striped : 3 spotted : 1 striped and spotted

Explanation:

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
