Proteins are polymers of molecules called amino acids, some contain thousands. Lipids are formed when a glycerol molecule combines with compounds called fatty acids, therefore they are not polymers because they contain one molecule and are not macromolecules

Because they are not made up of monomers.

In horses, the allele for a black coat (B) is dominant over the allele for a brown coat (b). A cross between a black horse and a

Answer:

Bb X bb

Explanation:

It is given that the allele B for the black coat is dominant over allele b for a brown coat.

A dominant allele always leads to the expression of the dominant trait in the heterozygous condition.

When a black and brown horse is crossed as given in the question and the result is a brown foal, then the genotype of the brown foal must be bb as the brown coat is a recessive trait.

Since each parent contributes one allele each for a given gene, the black horse must have b allele, and hence must be heterozygous Bb.
The cross is shown in the punnett square.
