It's the gene that would be heterozygous not the chromosome.
Heterozygous
heterozygous
An example could be mitochondria, because 1. Its not a chromosome and 2. It doesn't carry chromosomes.
Everyone is heterozygous at many genetic loci. It means the gene you got from your mother is different from the gene you got from your father. Since you got one chromosome (one gene) from each parent, there's a reasonable chance you'l be heterozygous in genes where there are different genes in the population. Depending on the gene, heterozygous can be an advantage - a "good" gene can overcome a "bad" gene.
Yes. Heterozygous dominance offers a way to preserve the mutated allele.
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
heterozygous
Only sex-linked recessive traits on the X sex chromosome are more common in males. This is because males receive only one X chromosome, so they cannot be heterozygous for a trait on the X chromosome. Females inherit two sex chromosomes, so they can be heterozygous, receiving both a dominant and a recessive allele on the X chromosomes.

Heterozygous is two different allelels for example the geno type Rr

Down's Syndrome is an example of a birth defect characterized by an abnormality of the chromosome structure.
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. =)
