It's the gene that would be heterozygous not the chromosome.
Heterozygous
The probability would be 0.5 or 50%. A heterozygous woman will pass on the X chromosome with the recessive allele to 50% of her sons, and since the disorder is recessive, the son would only have the disorder if the X chromosome with the recessive allele is inherited from the mother.
Chromosome # + pso the short arm of Chromosome 11 is referred to as 11p
Sickle cell disease is an example of codominance, not heterozygous dominance. In individuals who are heterozygous for the sickle cell allele, they exhibit a milder form of the disease called sickle cell trait, which demonstrates codominance of the normal and mutant hemoglobin alleles.
A chromosome can have both dominant and recessive genes for a specific trait, but only one gene will be expressed in an individual. The dominant gene will be expressed over the recessive gene in a heterozygous individual. This is known as the principle of dominance in genetics.
Human being is the best example for this type of inheritance because the gene responsible for colorblindness is present on the X chromosome. Thus a heterozygous female is the carrier of colorblindness and some of the sons from this mother receiving the X chromosome with a gene for colorblindness will be colorblind because in males the other sex chromosome is Y, which remains neutral for such genes.
Heterozygous
Chromosome Disorder
The probability would be 0.5 or 50%. A heterozygous woman will pass on the X chromosome with the recessive allele to 50% of her sons, and since the disorder is recessive, the son would only have the disorder if the X chromosome with the recessive allele is inherited from the mother.
Down's Syndrome is an example of a birth defect characterized by an abnormality of the chromosome structure.
In humans, an example of a heterozygous genotype would be Aa for blood type, where one allele codes for blood type A and the other for blood type B.
a heterozygous gene is a gene with a genotype with two different letters. For example, Hh rather then hh, HH (which are homozygous). Hope this helps. =)

if for example we had a yellow and a blue flower yellow being dominant (Y) and blue being recessive (y) a homozygous organism has the phenotype of either being YY or yy and a heterozygous organism could only be Yy.
