A nucleoside has two parts: a pentagonal sugar (deoxyribose) and a nitrogenous base (in color). When a nucleoside is joined to a phosphate, it is called a nucleotide. How many different nitrogenous bases do you see?

Anita thinks that she has heterozygous alleles for red hair.if she is correct, which of these diagrams best illustrates anitas alleles pf red hair

Explain the difference between incomplete dominance and codominance

Guinea pig coat color is determined by a single gene. the allele for black coat color is dominant to brown. in a cross between twoblack-haired guinea pigs, 20 offspring are born. if both parents were heterozygous, probability would predict that approximately howmany of the 20 offspring would have brown hair?
