Answer:
10 arrangements, although the parents have brown hair, they have a recessive allele for the blonde hair. The two brown heads can make a blonde or brown and or course even a red haired child. In this case the parents with dominant brown hair have a recessive blonde hair giving them a chance to have 10 arrangements to have blonde hair due to their recessive allele.
Explanation:
Heterozygous means that to have inherited different forms of a particular gene from each parent. In this case the children will inherit both brown and blonde hair genes.
Think about the actual physical process happening in the cell - the allele (or versions of a gene) are literally physical pieces of DNA strung together into chromosomes. And as the cell divides to form gametes, those chromosomes randomly assort themselves into the two new cells (conditional that each new cell gets one copy of each chromosome, in the case of gametes)...<span>

Both have phosphate-pentose back bone, as well as both have adenine, cytosine and guanine bases.
I believe it is called the cardiac muscle.
