They do not carry the sickle cell allele, a. Individuals that are heterozygous have the advantage of being more resistant to malaria than homozygous dominant individuals, but are not affected by the disease.
Huntington disease is autosomal dominant, meaning that individuals who inherit one copy of the mutant allele from either parent will develop the disease. Thus, individuals with Huntington's disease are heterozygous for the mutant allele. Homozygous individuals would not survive past a certain age due to the severity of the disorder.
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.

"Heterozygous" is not a disease. It is a term to describe the presence of two alternate alleles in a gene sequence.
There are not symptoms of heterozygous since it is not a disease or condition that you can get. It is a genetics term that refers to whether a gene is dominant or non dominate.

its a very rare disease because you have to be heterozygous to have it! I KNOW I'M CLEVER
If one of your parents is heterozygous for Huntington's disease, you have a 50% chance of inheriting the mutated gene responsible for the condition. This is because Huntington's is an autosomal dominant disorder, meaning that only one copy of the mutated gene is needed to develop the disease. If you inherit the normal allele from the heterozygous parent, you won't develop the disease.
Sickle Cell Anemia, in it's heterozygous form it does not present as the disease and it gives the carrier resistance to malaria.
No they are generally resistant to malaria
Something that grows fast and prolific and lasts a long time into cold wet weather. Mostly hybrids that have disease resistant parents.
