1) Firstly, lets sort out the alleles for the dominant and recessive characteristics. The dominant brown allele will be written as B and the recessive red hair allele will be written as b.
2) Lets sort out the genotype of the parents. The parent having homozygous brown coloured hair will carry the alleles BB. The parent carrying the heterozygous brown coloured hair will carry the alleles Bb.
3) The punnet square from these parents will be drawn as follows:
B b
B BB Bb
B BB Bb
4) Now, lets predict the phenotype of the offsprings. The results from the punnet square show that all of the offsprings will have brown coloured hair.
5) The genotype for the children will have 50% chance to be homozygous brown (BB) and 50% chance to be heterozygous brown (Bb).
It would become the same as another of starch component similar glycogen. Amylose as you mentioned have 1-4 bonds but glycogen have 1-6 bonds. Glycogen is more branched and this makes it less soluble in water. also it is used as a storage medium only and it is not easily digested. Just the level of complexity would have increased. solubility would have lessened
